the mutation fires, but the update is not triggering for some reason…

myNamedMuationCalledFollow({
        variables,
        update: (proxy, { data: { followersUser } }) => {
          console.log('this never triggers');
          const newData = proxy.readQuery({ getUserQuery });
          newData.followers.push(followersUser);
          proxy.writeQuery({ getUserQuery, newData });
        },
      });
