we use Talend to upsert a bunch of Accounts and Contacts(from the old archive) each night. Now im trying to also upsert the Account-Contact Relation.
Sadly my Talent Job always gives me this error: "INVALID_FIELD_FOR_INSERT_UPDATE:Unable to create/update fields: AccountId. Please check the security settings of this field and verify that it is read/write for your profile or permission set.:AccountId --".
Im running the Upsert with Admin permissions and on the Ui the fields can be updated. But in Workbench i cant see the two fields when trying to update. As far as i understand the two fields: "AccountId" and "ContactId" are not updatable. Is there a way to change that? I looked in sharing settings, on the Object itself,Permission sets and Profiles. Account and Contact are both read/write. Any help would be greatly apprichiated as i am a bit at a loss.
