DurableTaskClient.PurgeAllInstancesAsync causing a lot of warnings: 404 The specified container does not exist.

[JohanKlijn]

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)

cant repro it with durable isolated function with azure storage backend locally. screenshot shows the log:

Hi @JohanKlijn , can you check in your azure function storage account if any blob containers is missing? i think this may be related to large payload blob containers are missing when purging instances with large payload
