Would there be a downside to enabling grpc server reflection on the ledger-api?
Given that Postman has started supporting gRPC, and as of this version, they fixed a bug that prevented our protos to be imported, it would be neat if one could easily test/explore the LedgerAPI with Postman.
One way would be to grab all the protos from the repository and then import all of them individually.here .
Would it be sensible to enable this extension?

As far as I know grpc reflection is enabled. Running grpcurl against the ledger API exposed by daml sandbox works without any issues:

There was a bug in some older versions so make sure that you’re testing against 2.3.2.

I’ve just realized that it must be enabled by looking here

Hmm - then I’ll have to figure out why postman doesn’t like it.
Thanks @cocreature
