Botbuilder-dotnet: Bot Framework Fails to Create CosmosDb Container in Serverless Mode

[don4of4]

Version

4.10.3

Describe the bug

This bug is straightforward -- the cosmos connector does not work on the new serverless SKU, which is unfortunate.

To Reproduce

Steps to reproduce the behavior:
1.Create a serverless Cosmos DB

1. Attempt to write back state with a bot (1st time)
2. Error - Microsoft.Bot.Builder.Integration.AspNet.Core.BotFrameworkHttpAdapter: Exception caught : Response status code does not indicate success: 400 Substatus: 0 Reason: (Setting offer throughput or autopilot on container is not supported for serverless accounts.ActivityId: 46f6156c-5a06-41f8-9e67-dbba5a7d2298, Microsoft.Azure.Documents.Common/2.11.0, Windows/10.0.14393 cosmos-netstandard-sdk/3.2.1).

Expected behavior

I expect the library to successfully create containers in the cosmos DB instance.

@dmvtech can you look at this please?

Thanks @don4of4 I'm attempting to reproduce myself. Should be able to confirm tomorrow.

[don4of4]

Sounds good. It looks like the issue is just creation, so this should be a straightforward fix.

Yeah, I'm with you on this. Reproduced and in a agreement on very similar to #4310 . I'm assuming if it (options like ContainerThroughput, etc) was nullable, that this would no longer error.

Obviously, you're aware of the workarounds that @EricDahlvang has mentioned in that one, so I won't go into that here.

Thanks for bringing this to our attention.
