I'm a System Admin in an org and today our Flow was throwing errors saying no such field RecordType.DeveloperName. I tried running a SOQL query using that field in Developer Console and I get same error if I run the query using Tooling API. If I uncheck Tooling API query runs fine. The error from the Flow is below.
ERROR at Row:1:Column:8 No such column 'Developername' on entity 'RecordType'. If you are attempting to use a custom field, be sure to append the '__c' after the custom field name. Please reference your WSDL or the describe call for the appropriate names.
I can use the Tooling API in the SOQL to include all RecordType fields except the DeveloperName.
I don't know how these two errors are related but need to access RecordType.Developername in any case. Any thoughts on problem here?
