config ui schema

Error message

config ui schema

What it means

build_schema() converts the schema_for!(ConfigUiDocument) output to a serde_json::Value and unwraps. A schemars-generated schema of a plain struct is expected to serialize cleanly; failure indicates an incompatible schemars/serde_json combination or an exotic type in the document — a build/configuration bug.

Solutions

1. Check schemars/serde_json version compatibility in Cargo.lock
2. Remove non-representable types from ConfigUiDocument or adjust its schema attributes
