Error happens on an insert on a Custom Tag

Question

I have enabled Tags on a Custom Object and I am trying to insert a Tag by a following code

insert new CustomObject__tag(Type='Public',ItemId='a0023000000DtDuEAK',name='Custom Tag' );

When I execute the code I receive an error

System.DmlException: Insert failed. First exception on row 0; first error: INSUFFICIENT_ACCESS_ON_CROSS_REFERENCE_ENTITY, insufficient access rights on cross-reference id: []"

Usually this happens when a user doesn't have a Read permission to the corresponding record, but I am the owner of the record and have full access permission to custom object record.

How can I avoid this error?

Answer 1

Once Topics are enabled, Public tags are deactivated. To workaround this problem, a private tag can be created by using the following code

insert new CustomObject__tag(Type='Personal',ItemId='a0023000000DtDuEAK',name='Custom Tag' );

Defines the visibility of a tag.
Valid values:
Public — The tag can be viewed and manipulated by all users in an organization.
Personal — The tag can be viewed or manipulated only by a user with a matching OwnerId.
