We’ve created a data migration workflow that is supposed to transfer data from app A to app B using the Bubble App Connector. We’re only using the workflow API, not using the data API at all.

In the workflow, we’re making some data changes and then using the “Return data from API” action to return things of different data types that we want to migrate. We’re obviously authenticating using API keys, and ignoring privacy rules, to ensure there are no restrictions on what data is returned.

Here’s the issue: When triggering the action through App Connector in app B, all fields in things that are returned with the “Return data from API” action are empty except the unique ID. What’s weird is that when running the same action in the frontend, even with a logged out user, data is received as expected.

Has anyone else experienced this in the past? Feel like I’ve tried everything, and only option left is to use the API Connector instead. Desperately want to save myself the hassle of manually mapping all fields across 36 endpoints.

Here’s an example of data returned through “Return data from API”:

I had a similar problem, I used N8N to make this operation easier.
