We have tried to update the approved email, While accessing edit draft we could not edit and at the time we faced the "Unexpected Error creating a new draft" error(Screenshot attached).
It shows System error. We are trying to the whole day. But, Still we are facing the same error.
Please help to find out the error.
Have you cleared your cache? Have you tried accessing edit draft in the incognito/private browser window? I'd also recommend logging out of your Marketo instance, restart your system after cleaning the cache and then try creating a new draft.
May have something to do with the email template. Vaguely remember encountering a frustrating error a long time ago with the email draft where the template was the issue. Sorry couldn't be more helpful
Please file a Support ticket with the screenshot of that error message. It allows us to look into the log files to find more information about the error that is being thrown. You probably wont be able to discern much detail otherwise. Thanks!
