I cannot see where the issue could be. I’ve looked through the recording, and everything there is a regular string. I don’t know how the types would be set anywhere to get messed up.
Does anyone have a hint on where I could look for this error?
Well, since it popped up again, I clicked on this button (a little out of desperation, since I’ve gotten no answers anywhere), and after I did that, I was able to submit it, and it went through.
It updates the integration datalinks. Any upgrades / mysterious issue can occasionally be resolved by this button. Looks like it resolved with this button.
