You are a Claude-Mem, a specialized observer tool for creating searchable memory FOR FUTURE SESSIONS.

CRITICAL: Record what was LEARNED/BUILT/FIXED/DEPLOYED/CONFIGURED, not what you (the observer) are doing.

You do not have access to tools. All information you need is provided in <observed_from_primary_session> messages. Create observations from what you observe - no investigation needed.

<observed_from_primary_session> <user_request>When I start the ddv running "npm run dev", the electron app get started, but I get only a blank screen. this happens only on dev-pro env. Although I have the frontend and the backend from the monolith started, this problem happens.

here is the current console.log from devtools

The webpack dev-server compilation completes with warnings about Sass deprecation and libsodium __dirname mocking, but then fails with critical module resolution errors. The primary blocker is a module federation configuration issue where @tanstack/react-query (and related dependencies) are missing from the shared module scope. Secondary failures cascade from missing npm packages (@doctolib/ scoped packages that appear to be internal monorepo packages), suggesting a dependency installation or workspace resolution problem specific to this environment. The module path resolution failures affect form handling (react-hook-form), phone input functionality (cleave.js), document processing (@doctolib/tpf-* packages), and browser mocking (MSW + @mswjs/interceptors). The blank screen indicates the app failed to mount due to these upstream compilation failures.</narrative> <concepts> <concept>problem-solution</concept> <concept>how-it-works</concept> <concept>gotcha</concept> </concepts> <files_read> <file>app/assets/javascripts/components/base/form/DEPRECATEDPhoneNumberInput.jsx</file> <file>app/assets/javascripts/contexts/ReactQueryProvider.tsx</file> <file>app/assets/javascripts/components/doctor/shared/signin/AccountForm/AccountForm.tsx</file> <file>node_modules/cleave.js/react.js</file> <file>node_modules/pdf-lib/cjs/index.js</file> </files_read> <files_modified> </files_modified> </observation>

The webpack compilation errors shown in the console output originate from the monolith frontend running in dev mode, not the DDV. The monolith's webpack bundler is unable to resolve dependencies (@doctolib/ scoped packages, react-hook-form fallback for module federation @tanstack/react-query). The DDV displaying a blank screen is a symptom: the Electron app likely cannot initialize without the monolith frontend API or dependencies being available. The required npm packages (react-hook-form, @tanstack/react-query) are confirmed to exist in the worktree's node_modules, suggesting the issue is module federation configuration, shared scope setup, or module path resolution in the monolith's webpack configuration—not missing packages.</narrative> <concepts> <concept>gotcha</concept> <concept>how-it-works</concept> </concepts> <files_read> <file>doctolib-pro-desktop/package.json</file> <file>doctolib-pro-desktop/vite.config.ts</file> </files_read> <files_modified> </files_modified> </observation>

The webpack error "Shared module @tanstack/react-query doesn't exist in shared scope default" suggests module federation's shared scope is not properly configured to include @tanstack/react-query as a shared dependency. Similarly, the cascade of "Can't resolve" errors for @doctolib/ packages and their dependencies (cleave.js, fbjs, pdf-lib) indicates webpack's module resolution chain is breaking. The DDV displays a blank screen because the monolith frontend (running on localhost:3000 in dev mode) cannot complete its webpack compilation due to these module resolution failures, leaving the Electron app without a frontend to load.</narrative> <concepts> <concept>problem-solution</concept> <concept>gotcha</concept> </concepts> <files_read> <file>doctolib-pro-desktop/vite.config.ts</file> <file>doctolib-pro-desktop/config/profiles/config.dev.ts</file> <file>doctolib-pro-desktop/config/profiles/config.staging.ts</file> <file>doctolib-pro-desktop/config/profiles/config.production.ts</file> </files_read> <files_modified> </files_modified> </observation>

Any other root tag is a protocol violation.

PROGRESS SUMMARY CHECKPOINT

Write progress notes of what was done, what was learned, and what's next. This is a checkpoint to capture progress so far. The session is ongoing - you may receive more requests and tool executions after this summary. Write "next_steps" as the current trajectory of work (what's actively being worked on or coming up next), not as post-session future work. Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.

Claude's Full Response to User: react-hook-form is missing dist/index.esm.mjs — only the .map file is there, but the actual file was never written. Webpack resolves using the "import" condition which points to ./dist/index.esm.mjs, finds nothing, and fails.

★ Insight ───────────────────────────────────── - The package.json exports map uses separate conditions: "import" for ESM (webpack module resolution) and "require" for CJS (Node.js require). Webpack 5+ picks "import" by default, so a missing .mjs file breaks bundling even when the .cjs.js file is present. - Module Federation's resolving fallback for shared module @tanstack/react-query error is secondary: it fires because the initial webpack compilation failed, so MF never registered the shared scope, causing the runtime crash that blanks the screen. - Git worktrees share the .git directory but have their own working tree — node_modules must be installed separately per worktree. ─────────────────────────────────────────────────

The FHIR-2228-dmp-validation-import worktree has an incomplete yarn install — multiple dist files are missing from packages (react-hook-form/dist/index.esm.mjs, likely others). That breaks webpack compilation, which breaks Module Federation shared scope registration, which causes the blank screen in DDV.

Fix:

cd /Users/USER/workspace/doctolib/worktrees/doctolib/FHIR-2228-dmp-validation-import
yarn install

Then restart the webpack dev server (Rails + rspack), and the monolith will compile cleanly. DDV should load normally after that.

If you want to verify the extent of missing files before reinstalling:

find /Users/USER/workspace/doctolib/worktrees/doctolib/FHIR-2228-dmp-validation-import/node_modules -name "*.map" | while read f; do base="${f%.map}"; [ ! -f "$base" ] && echo "MISSING: $base"; done 2>/dev/null | head -20

  <request>Diagnose why DDV Electron app shows blank screen when running npm run dev on dev-pro environment with webpack errors in monolith frontend.</request>
  <investigated>
    - Examined webpack console errors reporting missing modules (react-hook-form, @tanstack/react-query, @doctolib/* packages)
    - Verified that reported "missing" packages actually exist in worktree node_modules with properly built dist/ directories
    - Checked package.json configurations for react-hook-form, @doctolib/tpf-cda, @hookform/resolvers, and others
    - Confirmed packages have correct main/module fields (react-hook-form) or modern exports fields (@doctolib/tpf-cda)
    - Inspected actual dist/ directory contents for react-hook-form, finding only .map files for ESM entry point
    - Determined the issue affects DDV (Vite/Electron) indirectly through failed monolith webpack compilation
  </investigated>
  <learned>
    - The blank screen is caused by monolith frontend webpack compilation failure, not DDV itself
    - react-hook-form exports field uses "import" condition pointing to ./dist/index.esm.mjs, but the .mjs file is missing (only .map exists)
    - Webpack 5+ prioritizes "import" condition for ESM resolution; missing .mjs file causes webpack to fail even though .cjs.js entry point exists
    - Module Federation shared scope error is secondary: webpack never completes compilation, so shared modules never register, causing runtime crash
    - Git worktrees have separate working trees but share .git; node_modules must be installed separately per worktree
    - The root cause is incomplete yarn install in the FHIR-2228-dmp-validation-import worktree (multiple dist files missing from packages)
  </learned>
  <completed>
    - Root cause identified: incomplete yarn install leaving missing .mjs/.js dist files
    - Confirmed packages are properly configured but incompletely built
    - Diagnosed that issue is worktree-specific (dev-pro environment is this worktree)
  </completed>
  <next_steps>
    - Run `yarn install` in the worktree to complete package builds
    - Verify dist files are generated (can use find command to check for missing .js files where .map files exist)
    - Restart webpack dev server (Rails + rspack) in monolith
    - Verify DDV loads normally after monolith compilation succeeds
  </next_steps>
  <notes>
    The confusion in initial diagnosis came from conflating two separate applications: DDV (Electron/Vite) and monolith (Rails/webpack). The webpack errors were from the monolith frontend, not DDV. The issue is not missing npm packages from package.json, but incomplete build artifacts in node_modules after installation. The "dev-pro env" refers to the git worktree, which has isolated node_modules that require their own dependency installation and build process.
