Fix confusing 400 errors when uploading skills to Anthropic API - first error is wrong, second error is still misleading Includes evidence for Anthropic API troubleshooting demand.
SKILL.md file must be exactly in the top-level folder. Understand which specific Anthropic usage limit was hit and when it resets; identify actionable guidance for quota management Includes evidence for Anthropic API troubleshooting demand.
You've reached your usage limit. Please try again later. (no limit type identifier, no reset time) Fix Anthropic Claude API 413 rejection when sending documents via Vertex AI proxy — payload well under documented 32MB limit but consistently rejected Includes evidence for Anthropic API troubleshooting demand.
Error code: 413 - 'Request exceeds the maximum allowed number of bytes. The maximum request size is 32 MB' (but payload is only ~2MB) Handle transient overloaded_error SSE events gracefully with auto-retry and user-friendly message instead of showing raw JSON error in chat UI Includes evidence for Anthropic API troubleshooting demand.
SSE error returned from server: '{"type":"error","error":{"details":null,"type":"overloaded_error","message":"Overloaded"},"request_id":"req_..."}' Fix AttributeError crash when Anthropic Bedrock streaming returns a rate_limit_error SSE event on the first frame Includes evidence for Anthropic API troubleshooting demand.
AttributeError: 'NoneType' object has no attribute 'model' / 'usage' when receiving type=error SSE frame with rate_limit_error Fix Anthropic Managed Agents API rejecting all Claude models with 'model is not supported' error despite working on standard Messages API with same key Includes evidence for Anthropic API troubleshooting demand.
model is not supported (on agents.create() or sessions.create() via Managed Agents beta API, while same models work on Messages API) Fix Anthropic MCP connector beta returning wrong content block type (tool_use vs mcp_tool_use) causing tool invocation failures in LLM agent tool declarations Includes evidence for Anthropic API troubleshooting demand.
MCP connector: model intermittently emits tool_use instead of mcp_tool_use for tools declared in mcp_toolset with configs.<tool>.enabled: true Handle Anthropic API server-overloaded / rate-limit errors in production workflows to avoid blocking LLM-powered applications Includes evidence for Anthropic API troubleshooting demand.
APIResponseError: Request too fast, try again later. Anthropic overloaded_error Fix Anthropic SDK for Bedrock so error SSE events (rate_limit_error, model_not_found) are properly decoded as error events rather than being misclassified as completion events Includes evidence for Anthropic API troubleshooting demand.
AWSEventStreamDecoder emits every decoded frame as ServerSentEvent(event=completion) even for Bedrock error payloads like rate_limit_error and model-not-found, causing client code to process error events as completions Handle streaming SSE errors gracefully when using Anthropic API via AWS Bedrock (e.g., unexpected disconnection, malformed SSE frames) Includes evidence for Anthropic API troubleshooting demand.
Bedrock streaming SSE events errors are not handled gracefully — causes unhandled exceptions and dropped responses during streaming calls via Bedrock proxy Fix intermittent streaming disconnections (RemoteProtocolError) on long-running /v1/messages API calls with code_execution and tools Includes evidence for Anthropic API troubleshooting demand.
RemoteProtocolError — Streaming /v1/messages drops mid-stream during long code_execution + skills runs, losing partial responses Fix Anthropic Claude API rate limit 429 errors on Claude 3 Sonnet/Turbo/Haiku Includes evidence for Anthropic API troubleshooting demand.
anthropic.api.errors.RateLimitError: You exceeded your current capacity, using a free tier key. To increase your limit, upgrade to a paying plan. Fix Anthropic Vertex AI 413 error rejecting legitimate payloads under 32MB; differentiate between real prompt length limits vs incorrect rate-limit misreporting as 413 Includes evidence for Anthropic API troubleshooting demand.
Error code: 413 - Prompt is too long (when payload is only ~2MB, well under documented 32MB limit) API consumers hit Anthropic's overloaded_error, rate limits, or quota errors during production use. Need specific fixes for each error type to maintain API reliability Includes evidence for Anthropic API troubleshooting demand.
anthropic overloaded_error OR rate limit exceeded OR quota exhausted Fix unexpected 429 errors on Claude Code Max plan even when dashboard shows sufficient available quota; requires debugging discrepancy between dashboard counters and actual API enforcement. Includes evidence for Anthropic API troubleshooting demand.
rate_limit_error: 429 Rate Limit Exceeded despite dashboard showing available quota Fix rate limiting triggered by running multiple Claude Code instances concurrently; user wants to know if concurrent usage reduces per-session rate limits. Includes evidence for Anthropic API troubleshooting demand.
429 rate limit errors running multiple Claude Code sessions in parallel Developers using the new mcp_toolset beta feature encounter intermittent parsing errors when model returns generic tool_use events instead of expected mcp_tool_use events Includes evidence for Anthropic API troubleshooting demand.
model intermittently emits tool_use instead of mcp_tool_use for tools declared in mcp_toolset Get proactive notifications via alerts or webhooks before Anthropic API session or weekly budget caps are reached, enabling proactive scaling or budget management Includes evidence for Anthropic API troubleshooting demand.
No built-in mechanism to receive alerts or webhooks before session/weekly budget limits are exhausted — users discover rate limits only after hitting 429 Fix intermittent AttributeError crash in AsyncAnthropicBedrock streaming when first SSE event is a rate_limit_error; users cannot access event.message.model or event.message.usage because message is None Includes evidence for Anthropic API troubleshooting demand.
AttributeError: 'NoneType' object has no attribute 'model'; AttributeError: 'NoneType' object has no attribute 'usage' — triggered by Bedrock SSE error payload {"type": "error", "error": {"type": "rate_limit_error", "message": "Rate limited"}} Add proper error handling for malformed/corrupt SSE events during streaming when using Anthropic SDK with AWS Bedrock backend Includes evidence for Anthropic API troubleshooting demand.
Bedrock streaming SSE events errors are not handled gracefully
