Hi @2cl
Welcome to the Community! I'm sorry you’re having trouble with your Zap.
Upon checking, it looks like you’re running into a bug. I added you to the bug report and I see it is still an active bug. Besides that I don't have any updates, unfortunately. Since this integration is owned by MailerLite, I am not able to see if they are actively working on it or not. You may want to reach out to their support team as well as hearing about issues from your customer always carries more weight.
Thanks. I was able to successfully migrate all of my other MailerLite zaps except those using this trigger. Will I receive a notification when there is an update to the bug report?
Hi @2cl
That’s great that you were able to migrate the other MailerLite Zaps successfully.
You will still receive a notification when an update has been made.
Hi @brem
I tried updating my zaps today that were previously giving the errors for the Subscriber Completed Automation event and was able to do so successfully. Does the bug report show if this issue is now resolved, as it appears to be on my end? Thanks!
Hi @2cl
Great to hear that you’re issue has now been resolved! We appreciate your effort in trying resolutions.
As per checking the bug report, it doesn’t seem to be fixed yet and we can’t provide an exact timeframe of when this will be resolved. But since you’re already added, we’ll notify you via email if it is.
Thank you. Let me know if you have other questions!
