Background information
We were trying to just run a empty bot on a alpine dotnet7 runtime base image in docker.
However we were immediately greeted with the error:
18:55:47 Gateway Connected
18:55:47 Gateway Error handling Dispatch (GUILD_AVAILABLE):
System.Globalization.CultureNotFoundException: Only the invariant culture is supported in globalization-invariant mode. See https://aka.ms/GlobalizationInvariantMode for more information. (Parameter 'name')
en-US is an invalid culture identifier.
at System.Globalization.CultureInfo..ctor(String name, Boolean useUserOverride)
at Discord.WebSocket.SocketGuild.Update(ClientState state, Guild model)
at Discord.WebSocket.SocketGuild.Update(ClientState state, ExtendedGuild model)
at Discord.WebSocket.DiscordSocketClient.ProcessMessageAsync(GatewayOpCode opCode, Nullable`1 seq, String type, Object payload)
We then figured out that Discord.NET requires en-US as a culture. So the fix was simple:
Add <InvariantGlobalization>false</InvariantGlobalization> to your csproj
and add RUN apk add --no-cache icu-libs to your dockerfile.
That then fixed the issue we had so far, however I was questioning why it would require cultures. I think it should support running with invariant culture aswell.
So after talking to someone on the discord server about it they said it has the following reason and told us to open a github issue about it.
eggsbox on Discord.NET's discord server:
It's for registerring the PreferredCulture for a guild based on the Locale
so with it running in InvariantMode; and alpine having no cultures, it couldn't load it and dnet isn't safely catching it
I'd suggest raising it as an issue on the github with your stack trace.
Feel free to request any more information / reach out.
