Joplin Export yields "Export failed, see developer console" error, even after Manage and token paste/save show working properly.

What is written at the developer console? It would be great if you could provide a bit more feedback (if possible at Github: https://github.com/marph91/thunderbird-joplin-export/issues) to solve this issue.
