I've been having this error for 4 days whenever I try to edit any mailbox in the email parser by Zapier:

 

I've tried everything, I've switched accounts, reset the browser, switched browsers and nothing works.
Is this happening only to me?

I’m having the same issue 7 Aug, contacted Zapier and received this:

And also thank you for raising this to our intention. It seems there is an issue with Email Parser by Zapier, that fails to load the parser.zapier.com/mailboxes/mailboxId website.

I can see that other users have also run into this issue, so I'm adding your email to the list of affected users. While we don't have a timeline on this, once this is resolved, we'll be sure to follow up via email to let you know—apologies for the inconvenience.

It’s still not resolved as of 11 Aug, I contacted them again but haven’t had a reponse.

Same issues since friday

same here, Do any found a workaround? I tried other email parsing but their free accounts are limited to 30 emails per month

I’m having the same problem. Just sent a support message. Two more threads on the same topic: 

Same issue. Hoping it is resolved shortly before I have to go find another option. Just messaged support. Here’s two more threads on the topic:

Me too, just need to fix a template as the emails have changed and I can’t :-(

Yeah, me as well. 

Hi All,
