InvalidState: "stream error"

[AlexeyRaga]

I am using bidirectional stepped client and sometimes get this error:

InvalidState "stream error"

I tracked it down to this line but it is not clear to me why it is happening.
https://github.com/haskell-grpc-native/http2-grpc-haskell/blob/master/http2-client-grpc/src/Network/GRPC/Client.hs#L229

Could you please point me to the right direction?

Hi Alexey,

A StreamErrorEvent is likely an HTTP2 level error (e.g., when trying to open a new stream when the server wants to close the connection -- as the HTTP2 protocol is asynchronous, there's no easy way to prevent this upfront). So it could be many things. However if you can reliably reproduce this error I'm really interested as it could be a bug in the HTTP2 lib triggering this.
