Hello. Seeing something a little odd, having updated a C# .NET WPF
application from GRPC 2.38.1 (22/06/2021) to 2.46.6 (11/01/2023).
The service I am receiving data from, has not changed.
When using version 2.38.1, I receive the data.
When using version 2.46.6, I do not receive the data, UNLESS I increase
'ChannelOptions.MaxReceiveMessageLength'. (Lazily, I am just setting to to
Int.MaxValue for now, and it fixes the issue).
The server is running an even older version (2.27.0), but I'm not sure that
is relevant.
It seems odd, given the data is the same. I can only explain it with an
assumption that the default value of 'MaxReceiveMessageLength' changed
between 2.38.1 and 2.46.6, and was reduced to tip us over the edge.
However, this too seems unlikely, and I couldn't see anything in the code,
prs, or docs on it. Apologies if I've missed it.
This is the error I see on v2.46.6 without support for larger messages:
System.AggregateException: One or more errors occurred.
(Status(StatusCode="ResourceExhausted", Detail="Received message larger
than max (4614213 vs. 4194304)",
DebugException="Grpc.Core.Internal.CoreErrorDetailException:
{"created":"@1744306302.187000000","description":"Error received from peer
ipv4:11.193.198.242:31510","file":"..\..\..\src\core\lib\surface\call.cc","file_line":953,"grpc_message":"Received
message larger than max (4614213 vs. 4194304)","grpc_status":8}"))
I get no error on 2.38.1.
Could it be possible that this check was not effective in earlier versions,
and someone fixed it, so that later versions now apply it correctly?
Does anyone have any ideas that might explain what it is I'm seeing? Thanks.
Howard.
