Error: Manifest Validation Failed - Breaking Changes Not Supported

Forge
1

I am encountering an issue while validating my Forge app manifest due to changes in the data structure. The error message I receive is:
Error: Manifest validation failed: Failed to validate custom entities
Additional information:

[
  {
    "message": "Property \"type\" of attribute \"nationality\" cannot be changed from \"string\" to \"any\"",
    "extensions": {
      "errorType": "BREAKING_CHANGES_NOT_SUPPORTED"
    }
  }
]

Here’s the relevant section from my manifest:

app:
  id: "ari:cloud:ecosystem::app/406d303d-0393-4ec4-ad7c-1435be94583a"

  storage:
    entities:
      - name: employee
        attributes:
          surname: 
            type: string
          age: 
            type: integer
          employmentyear: 
            type: integer
          gender: 
            type: string
          nationality: 
            type: any 
        indexes:
          - surname
          - employmentyear
          - name: by-age
            range: 
              - age
          - name: by-age-per-gender
            partition: 
              - gender
            range: 
              - age

Yes, unfortunately, it means exactly what it says. Currently, if you are using Custom Entities in Forge Storage, you cannot remove attributes, change the attribute types, delete entities, or perform several other related actions.
