Snowflake Output Connector - Tableau-CRM

Question

I am trying to use the Salesforce Analytics (Tableau-CRM) Snowflake output connector but getting the below error from Snowflake. SQL access control error: Insufficient privileges to operate on table stage 'TEST_NZ_EMP' when the JDBC 3.12.2 connector runs the below command.`

put file:///data/00Db0000000d/8Mo/.elt_maestro_elt.00Db0000000d8Mo.03C5p000003eKXMEA2_maestro_11149256732875375332/tmp03C5p000003eKXMEA2.896586859/GetFromGateway_g.38fe869b-0e3d-4500-87b0-45c2449898db/output-aggregate-folder25db8c0f-941b-4cfc-a049-fee9295e1d44/TEST_NZ_EMP_* @%"TEST_NZ_EMP"/qFgpy auto_compress=true overwrite=true;

The account has been given the following permissions using this article for instructions https://www.snowflake.com/blog/integrating-salesforce-data-with-snowflake-using-tableau-crm-sync-out/

GRANT USAGE ON DATABASE SYNC_DB TO ROLE SYNCOUT;
GRANT USAGE, CREATE TABLE, CREATE STAGE ON SCHEMA SYNC_DB.SYNCOUT TO ROLE SYNCOUT;
GRANT SELECT, INSERT, UPDATE, DELETE, TRUNCATE ON FUTURE TABLES IN SCHEMA SYNC_DB.SYNCOUT TO ROLE SYNCOUT;

Any suggestions on what other permission could be required? Thank you
