Adobe Experience Platform: meta:enum can not be empty

Run the List field groups  call from postman API collection which shows you all your field groups. Make sure to set the CONTAINER_ID to Tenant. For steps, refer to List field groups in our developer documentation.

Search among the list of field groups and find any that contain "meta:enum": {}.

For each of your field groups, follow steps 4-6.

Run the Retrieve a field group  call using the field group ID found in the list from step 2. For steps, refer to Retrieve a field group in our developer documentation.

Copy the whole response. An example of a field within the field group that has this issue:

"Profile Number": {
 "title": "Profile Number",
 "description": "Profile Number",
 "type": "string",
 "meta:xdmType": "string",
 "required": [ ] ,
 "meta:enum": {}
 },

and remove any lines that have "meta:enum": {}

Once the "meta:enum": {}  has been removed, it will look something like:

"Profile Number": {
 "title": "Profile Number",
 "description": "Profile Number",
 "type": "string",
 "meta:xdmType": "string",
 "required": [ ]
 },

Copy the response (that no longer has the "meta:enum": {}lines).

Run the Update a custom field group  call and paste the entire edited response from step 6 and send. For steps, refer to Update a custom field group in our developer documentation.

This will update that specific field group to no longer receive the error. Repeat steps 4-7 for each of the field groups that have this error.
