For the complete documentation index, see https://buildwithfern.com/learn/llms.txt. ## 1.25.0-rc3 **`(fix):`** Fix dynamic snippet and wire test generation for endpoints with bytes body and path parameters. Previously, the generator produced `nil` for the `io.Reader` body argument instead of a valid `bytes.NewReader([]byte(...))` call, causing wire test failures. Also fixed the nop request branch to include option arguments (e.g. test ID headers) in the method invocation, fixed path parameter resolution to use associateByWireValueOrDefault so missing path parameter values are synthesized, and fixed WireMock stub response generation to return an empty JSON object `{}` instead of a JSON string `""` when the example response body is null but the endpoint declares a named (struct) response type.
