If Gemini 3.8 Flash feels slow in Antigravity, first identify what is waiting: the first answer, an active tool, server capacity, a repeated command, or the app itself. Each calls for a different response.
Fix ChatGPT’s “Unknown Error Occurred” when uploading a PDF. Two file-and-browser checks help you choose a document, upload-limit, or connection fix.
A static page cannot prove that every Nano Banana 2 surface is up or down. Use the failing surface, its first-party status owner, and the exact error signal to classify the incident before retrying.
ChatGPT Plus has documented image-size and rolling file-upload boundaries, not one official 50-images-per-day guarantee. Find the active counter before retrying.
Keep the old thread, run one small prompt in a fresh chat, and let that control decide whether to hand off the work or troubleshoot the broader path.
This error is a request role-contract mismatch. Use the failing `param`, sanitized payload, current OpenAI Chat Completions or Responses shape, and a same-route smoke test to repair it safely.
OpenClaw Anthropic API key errors need an owner-first read: prove whether Anthropic auth is missing, the key is rejected, OAuth cannot refresh, an env var overrides config, the selected model is unavailable, or OpenClaw is only showing a provider cooldown after an earlier failure.
OpenClaw API key errors do not have one universal fix. Start with status, gateway status, logs, doctor, and models status, then route the error to the owner shown in the log: provider auth, gateway token, model cooldown, request shape, context pressure, or Docker environment override.
Getting context_length_exceeded in OpenClaw? First prove whether the request truly exceeded the selected model context window, or whether a rate-limit/fallback/cooldown path surfaced as a context error. Then compact, split the task, reduce tool output, trim workspace injection, or switch model routes.
OpenClaw's current provider layer no longer makes 'set beta_features to []' the right first answer. On modern builds, non-direct Anthropic-compatible endpoints suppress implicit Anthropic beta headers, Bedrock has its own AWS-auth provider path, and 1M context is only sent when `params.context1m` is explicitly enabled. This guide shows the current diagnosis path.
When OpenClaw shows 429 or rate limit exceeded, first identify whether the failing surface is the model provider, ClawHub download route, gateway cooldown, fallback chain, or context pressure. Each branch has a different fix.
A route-first recovery guide for the Gemini high demand error: identify the surface, separate 503 capacity from 429 limits and 504 timeouts, then retry or escalate with useful evidence.
A fast route board for the Grok heavy-usage message: status first, one surface switch, paid-plan recognition, bounded retry, and support evidence.
Nano Banana Pro can return HTTP 503 UNAVAILABLE even when the message says `Deadline expired before operation could complete`. The fastest fix is to classify the branch by code and status first, then retry, raise timeout, or leave the 503 page based on the actual error class.
A rapid-recovery guide to the Nano Banana Pro `RESTRICTED by System Instructions` message across Gemini Apps, AI Mode, and the Gemini API.
If Nano Banana Pro says "Unsupported file URI type," the useful first move is to identify the rejecting Gemini surface. Native Gemini `file_data`, OpenAI-compatible `image_url`, GCS registration, public URLs, and local file paths do not share one URI contract.
If OpenAI says your file type is not supported and tells you to try again with a PDF, the useful first move is to identify the rejecting surface. Current official OpenAI docs are not blanket PDF-only, but some lagging Azure or connector paths still behave that way.
An OpenClaw 401 is not one generic bad-token problem. This guide separates `invalid bearer token`, `missing authentication header`, and one-agent credential failures so you can apply the smallest correct fix without breaking what already works.
Grok authentication failure usually means one of four things: a live xAI outage, the wrong xAI sign-in method, an X login or 2FA failure, or an account-state problem like a temporary lock. This guide shows the correct recovery order with official xAI and X support steps.
If you are seeing "Grok is experiencing issues" or "Grok is Temporarily Unavailable," start with xAI's official status pages. As of the latest official check on March 28, 2026, Grok Web, X, iOS, and Android all showed fully operational, but recent incidents prove real outages do happen. This guide shows how to tell a global outage from a single-surface problem or a local browser and app issue.
A complete diagnostic guide for all Gemini image API errors: 429 rate limits with 4 root causes, silent generation failures with no error message, and parameters that get accepted but silently ignored. Includes production-ready Python and JavaScript code with full error handling.
When Nano Banana 2 (gemini-3.1-flash-image-preview) returns HTTP 200 OK but no image, the cause is almost always the IMAGE_SAFETY Layer 2 filter — and Google charges you the full token cost even though you received nothing. This guide explains the dual-layer safety architecture, quantifies the billing impact, and provides 7 proven prompt engineering strategies plus production-ready error handling code.
blockReason OTHER in Nano Banana 2 (Gemini 3.1 Flash Image) means your request hit Google's Layer 2 non-configurable policy filter. BLOCK_NONE and OFF cannot bypass it. This guide covers the complete blockReason vs finishReason mapping, dual-layer safety architecture, 8 trigger categories, and 5 proven solutions with production-ready error handling code.
The Nano Banana 2 thought_signature error (400 INVALID_ARGUMENT) occurs when multi-turn API requests omit the thought_signature from previous responses. This guide covers every scenario: multi-turn image editing, streaming edge cases, parallel function calls, platform-specific fixes for Dify and CherryStudio, and the hidden dummy signature workaround.
