Aborted

but when I use 'grpc' module with same code, there is no abort.

Reproduction steps

invoke ClientReadableStream.cancel()

Environment

• OS name, version and architecture: [WSL Ubuntu 20.04.1 amd64]
• Node version [14.15.1]
• Node installation method [nvm]
• If applicable, compiler version []
• Package name and version [@grpc/[email protected]]

I believe this may be related to #1464.

Wrapping the .cancel() call with setTimeout/setImmediate seems to mitigate the error.
