When trying to connect Bullhorn ATS in a Zap, after almost an entire year of a successful integration, it quit working with the error, “Cannot read property of 'args' field.”

Thanks to a response from the Bullhorn customer support team and working with Zapier, the solution was updating my Bullhorn password to not include the special characters %, &, £, #, ? or *. After I updated my password, the connection was enabled again and all zaps seem to be firing. 

Posting in case this tip is useful to anyone else, as it is not self-explanatory and doesn’t seem to be documented.
