This error repeats for 3 different upload attempts:

mbox-import-1766678400450@mbox.local

Root cause: The uploadedFilePath property is undefined when MboxConnector.fetchEmails() tries to retrieve the uploaded mbox file from storage.
Additional context
the error occurs at MboxConnector.fetchEmails line 79
