For the complete documentation index, see https://buildwithfern.com/learn/llms.txt. ## 0.36.6 **`(fix):`** Fix generated Rust wire tests for single-URL SDKs and pagination error tests. The wire test generator no longer emits `config.environment = None;` when the SDK was generated against a single base URL (since the `environment` field does not exist on `ClientConfig` in that case). The synchronous-paginator error-propagation tests now use `ApiError::Configuration` instead of the non-existent `ApiError::Serialization` variant, so the generated `pagination.rs` test module compiles.
