I have been trying to use the Row filtering and Column masking feature to redacted columns and and filter rows based on the group a user is in.

I have all the necessary permissions and I've used cluster's with version 15.4 and higher.

When I run the following statements 

ALTER TABLE testtable_new ALTER COLUMN payload SET MASK payload_mask;

ALTER TABLE testtable_new SET ROW FILTER row_filter ON (payload);

 I get the this error

UnityCatalogServiceException: [RequestId=48187b09-7063-42e2-9b12-643717b0eb91 ErrorClass=ABORTED.UC_DBR_TRUST_VERSION_TOO_OLD] The Databricks Runtime being used no longer supports this operation. Please use the latest version (you may just need to restart your cluster).
