marshal request body: %w

Error message

marshal request body: %w

What it means

json.Marshal of the outgoing Notion API request body failed in doRequest. Since bodies are struct/map values built in code, this indicates an unsupported type (e.g. channel, func, or cyclic data) was passed as the request body.

Solutions

1. Check the body argument for unsupported value types
2. Ensure nested values are JSON-serializable structs/maps
3. Marshal the body once at construction to fail fast
