INSUFFICIENT_ACCESS_ON_CROSS_REFERENCE_ENTITY when subscribing role members to a record

Question

I created a trigger that on a record creation (Custom sObject), subscribes all the createdBy role members to the record.

This code seems to work just fine when executed by a sys admin, but it throws the following error for a user with Chatter Only profile.

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

What I'm missing here ??

Answer 1

It was me! I forgot to remove the "With sharing" keyword from the class definition. My bad!

Answer 2

Chatter Only profile might not be having sufficient permissions like create,read,update and delete permissions. once check those permissions.
