GRPC within service worker / web worker

Im trying to run GRPC from inside a service worker. It works fine from inside the main application thread and only throws an error from inside a service worker.

````typescript
const media = new MediaServiceClient(process.env.VUE_APP_GRPC)
media.index(pagination, headers)
````

Error:
````
Uncaught (in promise) TypeError: e.serializeBinary is not a function
````

Im assuming this is due to how GRPC communicates to the backend services and assuming this is not possible to do at the moment?

Thanks
