I get a NullReferenceException here when a request fails due to mapping being null. It looks like calling proxyHelper.SendAsync returns null for a mapping if the status code was not successful. The next if statement right below this also has the same issue.

Hello @CoderNate ,

Thanks for the information.

However I think you mean that these line can fail:

 _options.Mappings.TryAdd(mapping.Guid, mapping);

// and

 _mappingToFileSaver.SaveMappingToFile(mapping);

Correct?
