Troubleshooting & Error Codes

Solutions for the most common issues encountered when using LlamaParse. Error code reference tables are at the bottom of this page.

Authentication & API Keys

401 Unauthorized on every request

• Verify your API key is valid and not revoked in the dashboard.
• HTTP API: Check the header format: Authorization: Bearer llx-...
• Python SDK: Ensure LLAMA_CLOUD_API_KEY is set in your environment, or pass api_key="llx-..." to the client constructor.
• TypeScript SDK: Ensure LLAMA_CLOUD_API_KEY is set, or pass apiKey: "llx-..." to the client.
• Verify you’re hitting the correct regional API endpoint — a key created in NA won’t work against the EU API, and vice versa. See Regions.
• API keys are project-scoped — confirm the key belongs to the project you’re targeting.

403 Forbidden when accessing a resource

• The resource belongs to a different organization or project.
• Your role may not have sufficient permissions — check with your org admin.
• Your project may have been disabled by an administrator.
• For BYOC deployments, verify your OIDC configuration (token audience, required scopes, SSL settings).

Region & Base URL

Getting errors when using the EU region or BYOC

• EU region: Set the base URL to api.cloud.eu.llamaindex.ai. In the Python SDK: LlamaCloud(api_key="llx-...", base_url="api.cloud.eu.llamaindex.ai"). See Regions.
• BYOC: Set the base URL to your custom deployment endpoint. Ensure your OIDC provider is configured correctly (audience, scopes, SSL).
• API keys are region-specific — a key created in NA cannot be used with the EU endpoint.

File Upload Issues

File upload fails or times out

• Check file size against product-specific limits.
• Verify the file format is in the supported types.
• Ensure the file is not empty and has a filename.
• For large files, ensure a stable network connection — uploads are not resumable.
• Check Rate Limits for current per-endpoint limits.

File type not supported error

• Verify the file extension matches a supported format.
• Password-protected or DRM-encrypted files cannot be processed — remove protection before uploading.
• Audio files (mp3, mp4, wav, m4a, webm) are auto-detected by extension — no special mode is needed.

Parsing Problems

Parse job is stuck or taking too long

• Complex documents with many images take longer, especially with OCR.
• Check job status via the API or dashboard.
• If using Agentic or Agentic Plus tiers, try Cost-effective (3 credits/page) first — it still uses AI and produces markdown, but processes faster.
• Use target_pages (e.g., "1,3,5-8") to parse only the pages you need instead of the full document.
• Disable features you don’t need (e.g., image extraction, specialized chart parsing) to speed up processing.

Poor parsing quality or missing content

• Upgrade tier gradually: Cost-effective (3 credits) → Agentic (10 credits) → Agentic Plus (45 credits). Each tier uses more sophisticated AI models. Note: Fast tier (1 credit) outputs spatial text only, not markdown.
• Add layout extraction (+3 credits/page) for documents with columns, complex headers, or mixed structure.
• Use parsing instructions (parsing_instruction in v1, or agentic_options.system_prompt / user_prompt in v2) to guide the model. This only applies to AI-powered tiers (not Fast).
• For scanned documents, ensure image quality is sufficient for OCR. You can specify OCR language via processing_options.ocr_parameters.languages in v2.
• Content beyond 64 KB per page is silently truncated. Only the 35 largest images per page are processed. If your document hits these limits, content will be missing without an error. See Limitations.

Parse job timed out

• By default, parse jobs have no explicit application-level timeout — they run until completion. You can set timeouts via processing_control.timeouts in v2 (max: 30 min base + 5 min per page).
• Use target_pages to reduce the number of pages processed.
• Use Cost-effective tier instead of Agentic/Agentic Plus for faster processing with markdown output.
• Disable unnecessary features (image extraction, chart parsing) to reduce processing time.

Extraction Issues

Extraction returns empty or incorrect results

• Review your schema — field names and descriptions guide the model’s extraction. Be specific and unambiguous in descriptions.
• Verify your extraction target (PER_DOC, PER_PAGE, PER_TABLE_ROW) matches your document structure.
• If using Fast or Balanced mode, try Multimodal or Premium for visually complex documents. The default mode is Premium (highest accuracy).
• Check that the document actually contains the data you’re trying to extract.
• For pre-parsed files, extraction uses the cached parse result — if the parse quality was poor, extraction will be too.
• The root of your schema must be type: object with properties.

Schema validation error

• The schema root must be type: object with properties.
• Default values (other than null) are not supported.
• There are limits on total properties, nesting depth, character counts, and raw schema size. See Schema design and restrictions for the full list of constraints.

Classification Issues

Documents are misclassified

• Write specific, detailed rule descriptions (10-2000 characters). Precision matters more than length — include examples of what should and shouldn’t match within the description.
• Multimodal mode (2 credits/page) uses vision models on page screenshots instead of parsed text, which helps when visual layout matters. Note: Multimodal is only available in the v1 classify API.
• Ensure rule types are distinct — overlapping or vague descriptions cause ambiguity.

Rate Limits & Throttling

Getting 429 Too Many Requests

• See Rate Limits for current per-endpoint limits.
• Free tier organizations have a lower rate limit of 20 requests per minute.
• Implement exponential backoff with jitter in your retry logic (the API does not return Retry-After headers).
• For high-volume workloads, use the batch API to submit jobs in bulk rather than making many individual requests.

Webhook Issues

Webhooks are not firing

• Webhook URLs must be publicly accessible — the platform blocks delivery to private/loopback IPs (localhost, 192.168.x.x, 10.x.x.x, etc.).
• Check that the correct events are configured for your webhook.
• Webhooks retry up to 3 times with exponential backoff (1s, then 2s delays between attempts).
• Your endpoint must respond within 30 seconds with a 2xx status code, or the delivery is treated as failed.

Still Need Help?

• Check the LlamaParse Status Page for ongoing incidents.
• Review Limitations for current service limits.
• Contact support at support@runllama.ai or through your LlamaParse dashboard.

Error Reference

LlamaParse APIs return a JSON body with a detail field describing the error.

{
  "detail": "Human-readable error message"
}

For server errors (5xx), the response includes a correlation ID — include this when contacting support.

Job failure reasons — these appear in job status rather than HTTP responses:

Error Type	Meaning	Resolution

• For 402 errors, check your credit usage in the dashboard under Settings > Billing > Usage.
• For 404 errors on jobs, verify the job ID and check that the job hasn’t expired.
• Check the Status Page for ongoing incidents before debugging further.
• Include the correlation ID (from 500 responses) when contacting support@runllama.ai.
