Add Evidences not working in the execution page whenever Zephyr is also installed

Attachments for evidences can only be attached by pressing "ctrl + v", but not by uploading a file.

The following error message appears:

 Cannot attach file <FileName>: No project could be found with id 'null'.

This seems to be an incompatibility between Xray and Zephyr. To reproduce this error Zephry needs to be installed in your Jira instance.
