Hi All,
We are getting "this.folderid" is null exception on email poling process model and failed to create process instance.
This issue is happening intermittently, on the same PM we have instances where process instances are successfully initiated.
We haven't configured any folder on the start node, as there was no requirement for us to capture the email attachments. However at times we will receive attachments.
The same email was successfully instantiating process instance on lower environments.
