Cannot read property 'rpcCall' of undefined

See original GitHub issue

Injector doesn’t work and fails with:

ERROR Error: Uncaught (in promise): TypeError: Cannot read property 'rpcCall' of undefined
TypeError: Cannot read property 'rpcCall' of undefined
    at inject.js:62
    at Array.map (<anonymous>)
    at window.__GRPCWEB_DEVTOOLS__ (inject.js:61)
    at new MyFunction (myFunction.ts:24)
    .......

I suspect it comes down to how I generate grpc-web client:

protoc \
  --js_out=import_style=typescript:$OUT_DIR \
  --grpc-web_out=import_style=commonjs,mode=grpcwebtext:$OUT_DIR ${FILE}

I was having the exact same error using the promise client. After upgrading protoc-gen-grpc-web to 1.0.4 it worked fine.

We could add a notice in the readme that the minimal supported version is 1.0.4.

It works with PromiseClient, see the example. What version of grpc-web are you using to generate the clients? The generator changed the implementation of the promise client. Can you try upgrading your protoc-gen-grpc-web plugin to the latest 1.0.4 release.
