Hi, I have a collection that used to work fine, but now when being fetched I’m getting a 400 error and weweb stops the workflow. The problem is, in Xano the request history shows that all of the requests are successful and the output is what I expect.

Here’s the weird part… when I go to the collection setup and fetch the data, it works perfectly, it just fails when a part of a workflow in a fetch collections action. And there are no inputs that the endpoint requires, so that cant be the problem either.

Any help here would be greatly appreciated.
