Submission of an add-on identical to an existing one fails silently with no issue closure

[XLTechie]

I submitted an add-on called versionCollector. Then, after sendJSON completed, I submitted the same one again, in issue #3262. The same problem can be seen with @nvdaes submission #3258.

Actual:

• The submission fails silently.
• No comment is posted.
• No PR is opened.
• The issue submitting the duplicate is not closed.

Further, according to the workflow run report, something in one of the CodeQL scripts is what is failing.

Expected:

• A comment should be posted stating that the add-on version being submitted already exists.
• The issue should then be closed.
