e.g.

Description with failing test case

I have an ECS service that when calling :SendMessage it will fail at times with

implementation of method: :-get-info of protocol: #'cognitect.aws.client/ClientSPI found for class: nil

I can't give you a snippet for this as this will only happen when the service is getting a lot of traffic but it doesn’t happen on normal loads

I have looked at container insides metrics and at no point have the container gone above 50% of CPU or Memory so I don't think it has to do with running out of resources.

Any suggestions you can provide on how to get around this issue will be really appreciated.

Even if you can't provide a snippet, can you provide a stack trace when this happens? There are a number of places in the code that call -get-info.
