After creating the Integration records and access tokens for connecting the NetSuite account, when we try to fetch a particular record data from the account an error is returned throwing a ‘Permission issue’.
The REST API role has the required permissions added in the role section.
If there is a workflow deployed to the record for which data has to be retrieved that contains a state added with ‘Return User Error’ based on various conditions, the records that satisfy this condition will not be fetched in the REST API.
The only solution is to remove the State or modify it so that it will work for the Role that uses the REST WebServices.
