Action schema should serialize

Error message

Action schema should serialize

What it means

Raised while resolving the JSON schema for a single named action: after cache lookup misses, the keymap action-schema generator is asked to produce the schema for the denormalized action name. Failure means schemars could not build/serialize the schema for that action's bindings — typically an unknown action name or a type whose schema generation errors.

Solutions

1. Verify the action name exists and matches a registered Zed action before requesting its schema
2. Log the failing action name alongside the serialization error to identify the offending type
3. Guard with an Option-returning helper and cache None for unknown actions to avoid repeated failures
