Research direction

Start with the provided PurgeAllInstancesAsync reproduction and inspect the Azure Function storage account associated with the client. Identify which blob container request returns ContainerNotFound, then determine whether the container should exist and whether the warning is expected or indicates a framework issue.

Written by the indexing model from the issue text.

Description

Not sure how to re-open an issue from durabletask-dotnet, but @YunchuWang told me to re-open issue https://github.com/microsoft/durabletask-dotnet/issues/475 here, if there is still a problem. So, because there is still a problem/question I re-open the issue here.

When running the code below I get a lot of warnings.

Code:

public async Task PurgeAllInstances(DurableTaskClient client, DateTime fromDate, DateTime toDate, IEnumerable<OrchestrationRuntimeStatus> runtimeStatus)
  {  
      PurgeInstancesFilter filter = new PurgeInstancesFilter(fromDate, toDate, runtimeStatus);
      PurgeInstanceOptions purgeInstanceOptions = new PurgeInstanceOptions();
      PurgeResult purgeResult = await client.PurgeAllInstancesAsync(filter, purgeInstanceOptions, CancellationToken.None).ConfigureAwait(false);
  
  }

Warning:

Severity level: Warning, Message: Error response [9c10a80f-58e6-4378-bcb8-035c7b056089] 404 The specified container does not exist. (00.0s)

@YunchuWang ask me: "can you check in your azure function storage account if any blob containers is missing?". I can, I have no glue for which containers to look. So please let me know what containers should/shouldn't exist.
