Current behavior

With a NestJS gRPC server that uses a interceptor, client stream calls are not working. If no interceptor is used, client streams work flawlessly. The same behavior occurs for bidirectional streams, but there are no bugs for server streams

Minimum reproduction code

https://github.com/hersentino/nestjs-grpc-interceptor

Steps to reproduce

1. npm i
2. npm start => run gRPC server
3. npm run client => run gRPC client that makes a client stream to the server => call not working
4. Comment out the gRPC interceptor on line 28 inside src/main.ts
5. Re-run steps 2 and 3 => call working fine

Expected behavior

To have the gRPC client stream working when an interceptor is registered
