I have an API Workflow endpoint in App 1 which requires a custom datatype (Amenity) from App 2. I then need to add/set a list of App 2’s data type.
Below is a snapshot showing the structure for the custom datatype (Amenity) in both apps:
Below is the workflow setup in App 2 (where I need to run the API workflow):
Once I attempt to run the API Workflow from App 2, to add/set a list of Amenities in App 1, the error message below shows:

Essentially, I want to modify data in App 1 from App 2. I understand and know how to do this when modifying standard datatypes like texts, numbers, images etc. However, I am struggling to do the same with custom datatypes from another Bubble app. The data structure for the custom data type in both apps are exactly the same (as shown in the second image).

Image A shows the Amenity List under the Property datatype in App 1.
Image B shows the stored data in App 2.
