Managed Second Generation Package version creation fails if the version has an ancestor and if the metadata has custom metadata type in it or when using ancestor and formula fields

1) Create version 0.1 of a managed package.

2) Promote the package version to released.

3) Create version 0.2 with 0.1 being the ancestor without making any change to the metadata.

Actual Results:

The package version fails with:

ERROR: obj1__c.f2_formula__c: Cannot modify managed object: entity=CustomFieldDefinition, component=00N19000002K6Qv, field=AggregateRelationshipName, state=released.

Expected Results:

Package version created for version 0.2 succeeds.

++++++++++++++++++ Repro with Custom Metadata types ++++++++

1) Create a 2GP managed package - sfdx force:package:create -t Managed -n 2GP-pkg1 -r force-app

2) Create a 2GP package version - sfdx force:package:version:create -p 2GP-pkg1 -x -w 15

3) Promote the package version - sfdx force:package:version:promote -p 2GP-pkg1@0.1.0-1

4) Update the sfdx-project.json and add this in the packageDirectories section - "ancestorId": "2GP-pkg1@0.1.0-1"

5) Create a 2GP package version - sfdx force:package:version:create -p 2GP-pkg1 -x -w 15


Package Version succeeds
