Adobe Experience Platform: meta:enum can not be empty

Description

Environment
Adobe Experience Platform (AEP)

Issue/Symptoms
When attempting to update a field group an error appears: Error at meta:enum of property ECID. The meta:enum can not be empty.

Resolution

As a workaround, locate the empty enum values, and then replace them:

1. 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.

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

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

4. 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.

5. 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": ,
                      },
   

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

7. 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.

8. 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.

To learn about the collection that contains these calls, refer to Postman collections in our Experience Platform Overview.
