Argument of type 'Handler' is not assignable to parameter of type 'UntypedServiceImplementation' - grpc_tools_node_protoc_ts

Upgraded to the latest and started getting the error message above when using the addService call. Noticed that in your example you are ignoring the compilation issue with the ts-ignore directive, is this a known issue?

Seems not, could you share some sample codes or proto file? Also the versions you are using. Including the grpc_tools_node_protoc.

Thanks. Great to see this fixed. It looks like we now have Type parity across the popular tools:

grpc-proto-loader
ts-protoc-gen
grpctoolsnodeprotocts

I'll update my example in https://github.com/badsyntax/grpc-js-types/tree/master/examples/grpctoolsnodeprotocts#issues-with-this-approach to show this latest change.

I'm not sure this is fixed. After updating to 5.1.0, I started getting TS compilation errors due to this change. VS Code expects the following to be in my implementation:

class MyServerImpl implements IMyServiceServer {
    [name: string]: grpc.UntypedHandleCall; // <== This line is expected...

    // But if I have properties / methods that are not RPC-handling like...
    data: Foo = ...;
    someOtherFunction() {...}
}

I get the following compiler error: Property 'data' of type 'Foo' is not assignable to string index type 'HandleCall'.ts(2411)
