Turn 1 — User

I need to deeply investigate the document viewing flow because our previous fix (changing invalidateQueries to refetchQueries) didn't solve the "Failed to load PDF file" error.

Investigate: 1. What happens when a user clicks "dokument anzeigen" - trace the complete flow: - Which component renders the view button - What gets called when clicked - How the document URL is generated - How the PDF viewer loads the file

2. The useDecryptedDocumentsShow hook behavior: - When does it actually make a network request - Does refetchQueries actually trigger it to refetch - What's the enabled condition - could it be preventing refetch

3. Document download path flow: - How is document.download_path generated - Is it a presigned URL or a direct backend endpoint - When is the presigned URL generated - at query time or before

4. Check for any other caching layers: - Browser cache - Service workers - CDN - Backend response caching

5. Look at the Imports.tsx component specifically since that's where the user sees the error: - How does it use useDecryptedDocumentsShow - Is there any condition that might prevent refetch

The fix we applied changed invalidateQueries to refetchQueries, but the problem persists. I need to understand WHY the refetch isn't working.

I'll conduct a deep investigation of the document viewing flow to understand why the refetch isn't working. Let me start by mapping out the complete flow.

…(truncated, 319 more chars)

Excellent! Now I have a complete picture. Let me create a comprehensive report:

DEEP INVESTIGATION REPORT: "Failed to Load PDF File" Error

I've conducted a comprehensive investigation of the document viewing flow in the Imports component. I found critical issues that explain why the refetchQueries fix didn't solve the problem. Here's what I discovered:

1. DOCUMENT VIEWING FLOW BREAKDOWN

User clicks "dokument anzeigen" (document view button):

Imports.tsx (line 212-217)
    ↓
useDecryptedDocumentsShow({
  document: selectedDocumentFromContext && 'id' in selectedDocumentFromContext ? selectedDocumentFromContext : null
})
    ↓
decryptedDocuments.ts (useDecryptedDocumentsShow hook)
    ↓
handleEncryptedDocument() in utils.js (line 156-226)

Critical Flow Path: 1. User clicks document → selectDocumentByIndex() called (Imports.tsx:312-345) 2. This updates selectedDocumentIndex → triggers useDecryptedDocumentsShow 3. Hook extracts document.download_path (decryptedDocuments.ts line 71): ``javascript return { file: undefined, url: document.download_path ||/doctor_app/documents/${document.id}` }

4. If document is encrypted, calls `handleEncryptedDocument()` (utils.js:156-226)
5. This calls `getDocumentFile()` which does: `fetch(download_path)`

---

### 2. THE ROOT CAUSE: Missing `download_path` on Initial Selection

**CRITICAL ISSUE FOUND:**

When a document is first selected in the Imports flow:

```typescript
// Imports.tsx line 213-217
const { data: decryptedDocument } = useDecryptedDocumentsShow({
document: selectedDocumentFromContext && 'id' in selectedDocumentFromContext ? selectedDocumentFromContext : null,
})

// selectedDocumentFromContext comes from documents[] which are DocumentImportsDocumentWithPreview
// These are LOCAL documents (just uploaded), NOT fetched from the backend API

The problem:

Locally uploaded documents in DocumentImportContext don't have a download_path field. They're temporary objects with: - id (document UUID from server response) - filename - localFileId - But NO download_path (that field is only populated by the backend API)

When useDecryptedDocumentsShow tries to fetch:

// decryptedDocuments.ts line 71
document.download_path || `/doctor_app/documents/${document.id}`

It falls back to /doctor_app/documents/{document.id}, but this is the encrypted document endpoint which returns raw encrypted bytes.

Then handleEncryptedDocument() tries to:

// utils.js line 171-176
encryptedFile = await getDocumentFile({...})
// This fetches from the fallback URL, gets encrypted data
// Then tries to decrypt with getResourceId

3. WHY refetchQueries DOESN'T FIX THIS

In documents.ts (line 559-562):

await queryClient.refetchQueries({
  queryKey: buildDecryptedDocumentQueryKey(documentId),
  type: 'active', // Only refetch if query is currently mounted
})

The problem with this approach:

1. refetchQueries doesn't re-execute the query if it hasn't changed. The query key is: ```typescript ['doctor_app', 'decrypted_documents_url', documentId]

2. **Even if it does refetch, the underlying issue remains**: The query function still receives the same `document` object with no `download_path`:

 ```typescript
 // decryptedDocuments.ts line 96-103
 const { queryKey, queryFn } = decryptedDocumentsShowQuery({
   account,
   decryptFile,
   document,  // Still the local document without download_path!
   httpClient,
   ...
 })

3. The enabled condition might be the real blocker (line 108): ```typescript enabled: Boolean(enabled && document?.id)

 This only checks if `document?.id` exists. Since the local document has an `id`, this passes. But the query still can't succeed because the document lacks proper metadata.

---

### 4. THE CACHE TIME PROBLEM

**In decryptedDocuments.ts (lines 14-15):**

```typescript
const DOCUMENT_STALE_TIME = 5 * 60 * 1000  // 5 minutes
const DOCUMENT_CACHE_TIME = 5 * 60 * 1000   // 5 minutes

Issue: If a document fails to load, React Query caches that failure for 5 minutes. Calling refetchQueries won't help because: - React Query sees the query is stale but still cached - It might not force a fresh fetch if the underlying data hasn't changed - The cache holds the error state

5. THE MISSING PIECE: Document Metadata Mismatch

The fundamental issue:

1. After upload, the server returns a minimal response with just document.id
2. For viewing, the UI should fetch the full document metadata including download_path
3. Currently, the code never fetches this metadata for newly uploaded documents

The refetchQueries approach assumes the document object already has all needed fields. It doesn't - it's a partially populated object.

6. WHERE THE FIX SHOULD BE

The real solution requires one of these approaches:

Option A: Fetch full document metadata on selection - When user selects a document, fetch /doctor_app/documents/{id}.json first - This populates download_path and other fields - Then pass this complete document to useDecryptedDocumentsShow

Option B: Include download_path in upload response - Have the backend return the presigned/direct download URL in the document create response - Store this in the local document object immediately

Option C: Fix the fallback URL logic - Ensure the fallback endpoint /doctor_app/documents/{id} works for encrypted file downloads - Debug why it returns 404 or wrong content

Option D: Bypass download_path entirely for local documents - Detect if it's a newly uploaded local document - Use a different flow that doesn't require download_path

7. CACHING LAYERS INVOLVED

• React Query Cache: 5-minute stale/cache time for decrypted documents
• Browser Cache: May cache 404 responses from failed fetches
• Presigned URLs: If using S3 presigned URLs, they expire and can't be re-used
• Service Workers: Could cache failed requests

KEY FILES INVOLVED

1. /Users/USER/workspace/doctolib/doctolib/app/assets/javascripts/components/doctor/desktop/pages/documents/Imports.tsx (lines 212-345) - Entry point for document selection

2. /Users/USER/workspace/doctolib/doctolib/engines/documents/app/assets/javascripts/queries/documents/doctor_app/decryptedDocuments.ts (lines 87-143) - The hook that needs fixing

3. /Users/USER/workspace/doctolib/doctolib/app/assets/javascripts/components/shared/documents/utils.js (lines 156-226) - handleEncryptedDocument() function

4. /Users/USER/workspace/doctolib/doctolib/engines/documents/app/assets/javascripts/queries/documents/doctor_app/documents.ts (lines 559-562) - Where the refetchQueries fix was applied

5. /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/financial_os_care_plan_sdk/src/types/DoctorAppDocument.ts (line 13) - Type definition shows download_path is optional

CONCLUSION

The refetchQueries to invalidateQueries change was targeting the wrong problem. The issue isn't about cache invalidation—it's that newly uploaded documents don't have the download_path field needed to fetch the file, so any refetch attempt with the same incomplete document object will fail. The fix needs to either:

1. Fetch the full document metadata before attempting to view it, or
2. Ensure the document object contains download_path from the upload response, or
3. Use a different mechanism for accessing newly uploaded documents that doesn't depend on download_path
