Report Error - sends email to an undefined email

While testing indico 2.2.7, the following error occurred when I tried to create a zip file of all the material, and some where not on the disk. Pressing the “Report Error” button sent the report to an undefined email (Sent email “[] Error report: OSError:”) and not to the configured SUPPORT_EMAIL = ‘’

Is there another email configuration variable that I need to create?
I have already reloaded the indico.conf several times and restarted all the services with the same result.
I would greatly appreciate your help.


No, it is sent to SUPPORT_EMAIL… Where do you see that it’s being sent to an undefined email?

This is from the indico.log file:

I don’t stee an undefined email there.

"[] Error report: OSError:" is the subject of the email that has been sent…

never received the e-mail though

Regarding the error itself I think it’s pretty much self-explanatory. And the zip archive creation will always fail if there are references to files that don’t exist on disk… (I wonder why that’s the case though)

this an error that i created to test the interface.

Usually the subject contains the SUPPORT_EMAIL, this is why I assumed that this email was send to Sent email "[]
