sObject ' ' type is not supported

Check that the Profile of the User you are using has at least Read Acess to the sObjects you are missing. Also I believe Assets need to be enabled by enabling Products, so worth checking that Products are enabled.

Also you are missing all the standard CRM objects like Account and Contact so worth checking what type of license is assigned to your user, you would need a Salesforce (CRM) license to be able to access the CRM objects.

Additionally, similar to Assets, certain objects become available only when the associated features are enabled eg Product Schedules

This may be a solution to this problem


For custom objects, it is also worth verifying that their Deployment Status is set to "Deployed" rather than "In Development"
