Export failing when using the Migration Utility Tool
Cause
As part of the new Migration Utility Tool feature, CLM (Contracts for Salesforce) introduced the new field APXT_Redline_External_Id_c to the following Clause Library objects:
Clause Bundle
Clause Type
Clause Category
Clause
Bundled Clause
Clause Configuration
Sub Clause
Alternate Clause
Clause Approver
Approval Step
Due to Salesforce limitations when using dynamic SOQL, the export function fails if there is a custom field called External_Id__c on any of these objects. The following Salesforce article references this issue: https://help.salesforce.com/articleView?id=000314137&type=1&mode=1
