I’ve been running into an issue trying to add profiles to a list in batches of 950. Things were working fine but I started to run into this error:
{:success=>false, :response=>{:errors=>[{:id=>"c8932474-507f-45e6-9d12-4a1a87403ae1", :status=>400, :code=>"invalid", :title=>"Invalid input.", :detail=>"Invalid profile IDs: set()", :source=>{:pointer=>"/data/"}}]}}
The endpoint is:
https://a.klaviyo.com/api/lists/{id}/relationships/profiles/
And I tried to keep my payload under 1000 so 950 per call. I’ve been able to successfully move 20,000 profiles into a list without issue but lately I’ve been getting the error above. Any ideas what might be happening? I was going to drop my numbers down to try to isolate which profiles might be failing. Would love any feedback if anyone has hit the same error.
