OpenClaw API Key Errors: Fix Missing Keys, 401, 429, and Gateway Auth

Nano Banana Pro "Unsupported File URI Type"? Fix the Gemini File Route

For "Unsupported file URI type," check the exact image value your app sent and the endpoint that rejected it.

Fix OpenClaw context_length_exceeded and Failed Compaction

For a large OpenClaw session, save the task state and try supported manual compaction. If the summary request also exceeds its limit, resume in a fresh session from a short record of completed work. Fresh-session failures require checking fixed overhead and the local model's loaded context.
