### 2. Create a sample OPA Policy

In another terminal, create a policy that allows root user all access and for all other users denies `PutObject`:

```sh
cat > example.rego <<EOF
package httpapi.authz

import input

default allow = false

# Allow the root user to perform any action.
allow {
 input.owner == true
}

# All other users may do anything other than call PutObject

                    // We want it to be triggered only when there're pending changes in the specific vcs root, i.e. GradleMaster/GradleRelease
                    triggerRules = "+:root=${VersionedSettingsBranch.fromDslContext().vcsRootId()}:."
                    branchFilter = "+:<default>"
                }
            }
        }
    }

        RuntimeCIFSException exception = new RuntimeCIFSException(message, cause);

        // Then
        assertNotNull(exception);
        assertEquals(message, exception.getMessage());
