grpc-web nodejs stream service limit?

[Danz]

I began with the tutorial https://grpc.io/docs/tutorials/basic/web/ and have been progressing nicely until a hard stop.

For some reason, my client/server implementation appears to be limited to about 7 server streaming rpc calls.

For example;

service status {

  rpc StreamOne(OneRequest) returns (stream OneReply);

  rpc StreamTwo(TwoRequest) returns (stream TwoReply);

  rpc StreamThree(ThreeRequest) returns (stream ThreeReply);

  rpc StreamFour(FourRequest) returns (stream FourReply);

  rpc StreamFive(FiveRequest) returns (stream FiveReply);

  rpc StreamSix(SixRequest) returns (stream SixReply);

  rpc StreamSeven(SevenRequest) returns (stream SevenReply);

  rpc StreamEight(EightRequest) returns (stream EightReply);

  rpc StreamNine(NineRequest) returns (stream NineReply);

}

I can pick any 7 rpc calls in any order from the above service and they work great.

No streaming is performed on any rpc after the 7th.

I'm using proto3, grpc-web, nodejs, envoy proxy, ngnix...

(:

Please advise

This is unexpected. Can you please log an issue to the grpc/grpc-web repo?
