client: object PUT stream handler misses unexpected OK response

[cthulhu-rider]

objects are put via gRPC client stream. Normally the server should respond with OK only after the stream is finished by the client (via Close)

Current Behavior

Write misses the unexpected OK response, and if user calls Write again, he receives following error:

rpc error: code = Internal desc = SendMsg called after CloseSend

This is a gRPC error when trying to send a message to a closed stream (what shouldn't happen)

Expected Behavior

when stream finish encountered, and the code is OK, return

server unexpectedly interrupted the stream with status OK

Possible Solution

neofs-sdk-go/client/object_put.go

Line 204 in 335d9fe

x.err = x.client.processResponse(&respV2)

x.err will be nil here. If so, return a stream violation error

Context

Client testing

Regression

No
