gRPC-Web Developer Tools conflicts with unary interceptors introduced by grpc/grpc-web #80
Description
I'v found that enabled gRPC-Web Developer Tools (by SafetyCulture) brokes up unary interceptors set up for grpc-web client. Interceptors are being not called when gRPC-Web Developer Tools are enabled.
Issue was found with next code:
const AuthInterceptor = function() {
this.intercept = function(request, invoker) {
request.getMetadata().Authorization = AuthService.GetAuthHeaderValue();
return invoker(request);
};
};
const options = {"unaryInterceptors": [new AuthInterceptor()]};
const APIClient = new APIPromiseClient(API_URL, null, options);
const enableDevTools = window.__GRPCWEB_DEVTOOLS__ || (() => {});
enableDevTools([
APIClient,
]);
APIClient.me(new ProtobufEmpty(), {})
.then(result => {
...
})
.catch(error => {
console.error(error); // <-- when gRPC-Web DevTools are enabled I receive error "no auth header" from my backend
});
