I have a gRPC service (not using TLS).
When I run grpcurl -plaintext localhost:50051 list , I get a valid response and can successfully interact with the service.
However, when I try using Postman or Insomnia, the request immediately fails with code 12: Unimplemented .
Why does it fail, and how can I get Postman or Insomnia to work?
Postman Version: 11.43.0
Welcome to the Postman Community! 
Do you have any specific details about how you’re setting this request up in Postman that you can share? Screenshots or videos would be extremely helpful 
In Postman, open the Console (bottom left in 11.43.4 Windows).
This will show you the exact request headers and body. You should be able to compare this to your curl to see the difference.
