I have Protected Custom Metadata Object Relationship field and I can't make it Unique. When I try to make it unique and generate a new validated package version, I receive the following error:
CustomMetadataMapping__mdt.TargetObject__c: Cannot modify managed object: entity=CustomFieldDefinition, component=00N1X00000Li061, state=MANAGED_RELEASED, Field: IsIndexed Previous Value: false New Value: true
I don't change any indexing here, why do I receive this error and have can I overcome this?
