3. /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/national-health-records/src/variants/types.ts

FOCUS: I need to understand the EXACT return value from useSearchDocuments. Specifically: - When the DMP API returns an error (timeout, access denied, etc.), does searchDocuments return { status: 'error', message: '...', data: [] } OR does it throw an exception OR does it return something else? - Look at the error handling in useSearchDocuments.ts carefully - is there a try/catch that might swallow the error without returning status: 'error'? - Does it return the monolith's SearchDocumentsResult type or the tpf type?

Also read: 4. /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/national-health-records/src/business/adapters/DmpNhrAdapter.ts (if exists) - to see how DMP errors are mapped

I'll read these files to understand the error handling in useSearchDocuments and how DMP API errors are handled.

Now let me look for the actual SearchDocumentsResult type definition in the main codebase:

Tools used:

• Bash: grep -r "export.*type.*SearchDocumentsResult\|type SearchDocumentsResult.*=" /Users/USER/workspace/doctolib/doctolib/packages/@doctolib --include="*.ts" ! -path "*/node_modules/*" 2>/dev/null

Tool results:

→ result (ERROR): Exit code 2

Tool results:

→ result (ok): (Bash completed with no output)

Based on my reading of the code, I can now provide a comprehensive analysis. The SearchDocumentsResult type is imported from @doctolib/tpf-national-health-records-ui in the variants/types.ts file, but let me determine what it actually is by examining the return types in the code I've already read.

Complete Report: useSearchDocuments Error Handling Analysis

Based on my thorough reading of the files, here is the complete picture of error handling in useSearchDocuments:

Return Type

SearchDocumentsResult is imported from @doctolib/tpf-national-health-records-ui and re-exported in /src/variants/types.ts. However, based on the code patterns in useSearchDocuments.ts and DmpNhrAdapter.ts, the actual return type has this structure:

{
  data: NhrDocument[]
  total: number
  status: 'success' | 'error'
  message?: string
  code?: string
}

ALL Error Handling Code Paths in useSearchDocuments.ts (lines 25-66)

Path 1: Feature Flag Mock (lines 26-29)

• Condition: nhr_document_list_search_mocked feature is enabled
• Returns: { data: filteredDocuments, total: filteredDocuments.length, status: 'success' }
• No error path here

Path 2: Missing Patient Data (lines 32-33)

• Condition: !ins or !nhrOperations
• Returns: { data: [], total: 0, status: 'success' }
• Note: This returns success, not an error, even when patient data is missing

Path 3: Try-Catch Block (lines 35-64) - MAIN ERROR HANDLING

This is where DMP API calls happen via queryClient.fetchQuery():

A. Successful result handling (lines 50-56) - If result is null: returns { data: [], total: 0, status: 'success' } - If result.status === 'error': returns the error result directly with message and code ```typescript if (result.status === 'error') { return { data: [], total: 0, status: 'error', message: result.message, code: result.code } }

- If successful: returns `{ data: result.documents, total: result.documents.length, status: 'success' }`

**B. Retry Logic (lines 44-47)**
```typescript
retry: (failureCount, error) => {
if (error instanceof Error && error.message.includes('DMPAccessDeniedByExcededThreshold')) return false
return failureCount < DMP_DOCUMENTS_MAX_RETRIES
}

• Special handling: Errors containing DMPAccessDeniedByExcededThreshold are NOT retried (immediate fail-fast)
• Other errors: Retry up to 3 times before failing

C. Catch Block (lines 57-64) - CRITICAL

catch (error) {
  return {
    data: [],
    total: 0,
    status: 'error',
    message: error instanceof Error ? error.message : undefined,
  }
}

• Important: This catches errors thrown by queryClient.fetchQuery() (e.g., if all retries fail)
• Returns: Error status with the thrown error message
• Note: No code field is set in the catch block (only message)

How DMP API Errors Are Mapped (DmpNhrAdapter.ts, lines 169-187)

The searchDocuments method in DmpNhrAdapter is what gets called via nhrOperations.searchDocuments():

async searchDocuments(props: NhrDocumentSearchProps): Promise<NhrDocumentSearchResult> {
  if (!props.patient?.nationalHealthIdentifier) {
    return { documents: [], status: 'error', message: 'patient_national_health_identifier_required' }
  }

  const apiSearchProps = toSearchProps(props)
  const apiResponse = await this.dmpApi.search(apiSearchProps)

  if (apiResponse.error) {
    return {
      documents: [],
      status: 'error',
      message: new DmpApiError(apiResponse.error).message,
      code: apiResponse.error.apiErrorCode,
    }
  }

  return toDocumentSearchResult(apiResponse)
}

Key points: - DmpNhrAdapter does NOT throw exceptions for API errors - It catches errors from dmpApi.search() and returns { status: 'error', message: ..., code: ... } - The DmpApiError wrapper formats the error message - Errors with DMPAccessDeniedByExcededThreshold in the message will trigger the no-retry logic in useSearchDocuments

Complete Error Flow Summary

1. DMP API Error (timeout, access denied, etc.) - DmpNhrAdapter catches it: returns { status: 'error', message: '...', code: '...' }

2. useSearchDocuments receives error result - Line 52 checks: if (result.status === 'error') - Line 53 returns: { data: [], total: 0, status: 'error', message: result.message, code: result.code }

3. If React Query itself throws (all retries exhausted) - Caught by catch block (lines 57-64) - Returns: { data: [], total: 0, status: 'error', message: error.message }

Answer to Your Specific Questions

Q: When the DMP API returns an error (timeout, access denied, etc.), does searchDocuments return { status: 'error', message: '...', data: [] } OR does it throw an exception OR does it return something else?

A: It returns { status: 'error', message: '...', data: [], total: 0, code: '...' } - NOT an exception. The adapter pattern converts all DMP errors to status: 'error' responses.

Q: Is there a try/catch that might swallow the error without returning status: 'error'?

A: No. All code paths in useSearchDocuments return an object with a status field - either 'success' or 'error'. There is no code path that swallows an error silently.

Q: Does it return the monolith's SearchDocumentsResult type or the tpf type?

A: It returns the TPF type from @doctolib/tpf-national-health-records-ui, which is re-exported in /src/variants/types.ts. The adapter is built to return TPF types, not monolith types.
