Reproduce the issue from the listed gRPC collection steps in Insomnia 11.0.0 and inspect the Select Method dropdown entry point; no source file or test is named in the report. Done means typing a method name after opening the dropdown searches or filters the available methods, with coverage added where the existing dropdown tests live.
