Pages function not binding to worker

I am trying to use a service binding to bind my page "function" to a worker.

When calling

env.myotherworker.fetch(req)

env.myotherworker.fetch(req)

env.myotherworker.fetch(req)

env.myotherworker.fetch(req) I get "Fetch API cannot load: <url provided in req>"
