Error: goaway Frame with Invalid Size when trying gRPC Request

[sigridjineth]

Symptoms

• When trying to send requests to gRPC endpoints for the evmos blockchain (using https://grpc.bd.evmos.org:9090), I encountered with the following error. connection error: hyper::Error(Http2, Error { kind: GoAway(b"", FRAME_SIZE_ERROR, Library) })
• I wonder what is the root cause of the error and how to deal with the error. thanks.
• The endpoint works well on the terminal

  
  export NODE=grpc.bd.evmos.org:9090
  grpcurl -d '{"'address'": "'$EVMOS_ADDR_3'"}' $NODE cosmos.bank.v1beta1.Query/AllBalances

{ "balances": [ { "denom": "aevmos", "amount": "19254711178107386863" }, { "denom": "ibc/ED07A3391A112B175915CD8FAF43A2DA8E4790EDE12566649D0C2F97716B8518", "amount": "63743" } ], "pagination": { "total": "2" } }

Hi there!

This is an error I'm assuming is arising in the generated code of cosmos-sdk-proto? (perhaps cosmos_sdk_proto::cosmos::bank::v1beta1::QueryAllBalancesRequest?)

Whatever the cause is, it's something out of our control, arising in the low-level HTTP/2 client.

Either there's some error with https://grpc.bd.evmos.org:9090 or a bug in Tonic, the gRPC library we use.

I would suggest trying to file this issue against Tonic and see if they might be able to assist: https://github.com/hyperium/tonic

@sigridjineth Did you find a solution for this issue? I am running into the same error with a very similar setup.

[tony-iqlusion]

Perhaps file an upstream error against Tonic? https://github.com/hyperium/tonic

[tony-iqlusion]

I don't think there's anything we can do here. Whatever the solution to this issue is needs to happen upstream from this project. Closing.
