Unknown key

Error message

Unknown key '{key}'

What it means

The catch-all arm of the key match in update(): any .set key that is not one of the recognized configuration keys (model, compress_threshold, rag_*, dry_run, function_calling, stream, save, highlight, etc.) triggers this generic validation guard. The input at fault is the unrecognized 'key' string.

Solutions

1. Check the spelling of the key against the list of supported configuration keys
2. Use the config list/display output to see valid key names
3. If a newer key is expected, update the application to a version that supports it
