TypeError sequence item 1: expected str instance, NoneType found

[ebdavison]

I did a little bit more digging and found the following that had a None in one of the values.

Not sure how it got in there nor how to fix it so I just removed it with delete() and now I can get a list again...

Any thoughts on how to fix this or even better a way for the function to NOT error 500 when a None is returned?

We could fix the admin by doing:

return ", ".join(map(str, message.to_addresses))

in the line you identified in the stack trace. If you could test that, that would really help.

In addition to that, you'll need to fix your code to ensure you aren't passing to=None, because that will cause issues down the line anyway.

I can test that. I thought all of my email sending code had a check for None already but I will also check for that as well to prevent future issues.

I have checked by DB and cannot find any email address records that are empty (None) so thought the best way to handle this is as recommended.

I have a PR open on this; any chance it can be reviewed?
