I have a Master-Detail relationship with Accounts and Locations.
I am able to create the child using upsert
, but when I try to update the Account__c
field I get
(INVALID_FIELD_FOR_INSERT_UPDATE: Unable to create/update fields: Account__c.
Please check the security settings of this field and verify that it is read/write
for your profile or permission set.)
Profile and permission set look OK, from what I can tell.
Using Restforce.
