MailerLite error: Required field "Subscriber Group" (group_id) is missing

I manage students in Airtable and email them from Mailerlite, using Zapier to connect between the two. I have two Zaps: one to add students to a Mailerlite groups, and another to remove them.

The Zap that is supposed to remove students from a group keeps triggering at the same time as the one that adds them (but it runs into an error, so thankfully no harm done: I just get an annoying amount of error emails from Zapier).

The adding zap is watching a ‘time last edited’ field; the removing zap is watching a DIFFERENT ‘time last edited’ field. I’ve checked and double-checked: the removing ‘time last edited’ field is NOT updating. I tested and retested the Zap, but when testing it (correctly) can’t find the records it triggered and errored over just minutes ago.

Any ideas?

Hey @Sigurdur130,

Before we dig deeper into this, could you please try reconnecting your Airtable account? Here:

After that, please try triggering the Zaps again and checking if the Zap will trigger unexpectedly after reconnecting.

Please give that a try and keep us posted!

Thanks! 😊

Thanks for the answer, ken.a. I’ve reconnected and triggered the ‘join course’ Zap. Usually the ‘leave course’ triggers in the next poll so I gave it 10-15 minutes, and it’s all good! Thanks for the fix ^^

I’d love to understand this: how / why did reconnecting my Airtable fix this? What did it actually change? Or is this a case of “just turn it off and then on again, it’s just magic”?

Neeeevermind. A new student joined and what do you know it, Zapier tried to remove them. I’m lost again. Any more ideas?

Hi @Sigurdur130 

Could you kindly send a screenshot of how you’ve set up the Zaps? This would allow me to check further.

(If there’s any personal information, kindly blur them.)

Looking forward to your response! 😊

Hey Charie, thanks for the answer! It was brought to my attention that the zap was doing exactly what it’s supposed to; I was just so focused on the fact that I had it watching a field for UPDATES, that the name of the trigger is ‘NEW OR updated record’. It was, of course, triggering on new records. I set it to watch a view and now it works exactly as it should =)
