We have a project were we have recently enabled the feature allowing one Contact to link to multiple Accounts. We followed the directions according to the release notes and in the Developer console I am successfully able to execute queries such as:
SELECT Id, AccountId, ContactId FROM AccountContactRelation
However, when I try and execute this query remotely, I simply receive the error message:
sObject type 'AccountContactRelation' is not supported.
All queries FROM Contact or Account are successful. Does anyone know what I have to do to be able to query against
I am not sure if it is relevant, but if I check the "Use Tooling API" checkbox in the developer console, I receive this same error for queries against AccountContactRelation, Contacts, and Accounts.
