Does anyone here have success/working

Does anyone here have success/working example how to mock convex hooks? I tried to follow the injection test example with fakeConvexClientfakeConvexClient from convex-helpers repo. But no matter how i try to set it up I get the error TypeError: Cannot convert object to primitive value at Object.localQueryResultTypeError: Cannot convert object to primitive value at Object.localQueryResult. This also happens if you run tests in the convex-helpers repo, so probably fakeConvexClientfakeConvexClient class is outdated...
