[REQUIRED] Expected behavior

The project builds

[REQUIRED] Actual behavior

tsc fails with:

node_modules/google-gax/build/src/clientInterface.d.ts:7:18 - error TS2320: Interface 'ClientOptions' cannot simultaneously extend types 'GrpcClientOptions' and 'GoogleAuthOptions'.
  Named property 'auth' of types 'GrpcClientOptions' and 'GoogleAuthOptions' are not identical.

7 export interface ClientOptions extends GrpcClientOptions, GoogleAuthOptions, ClientStubOptions {
                   ~~~~~~~~~~~~~

node_modules/google-gax/build/src/grpc.d.ts:24:18 - error TS2430: Interface 'GrpcClientOptions' incorrectly extends interface 'GoogleAuthOptions'.
  Types of property 'auth' are incompatible.
    Type 'GoogleAuth | undefined' is not assignable to type 'AuthClient | undefined'.
      Type 'GoogleAuth' is missing the following properties from type 'AuthClient': on, credentials, eagerRefreshThresholdMillis, forceRefreshOnFailure, and 16 more.

24 export interface GrpcClientOptions extends GoogleAuthOptions {
                    ~~~~~~~~~~~~~~~~~

src/index.ts:1:1 - error TS6133: 'functions' is declared but its value is never read.

1 import * as functions from "firebase-functions";
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Found 3 errors.

The last error is expected, given that this is a fresh empty project, but I can't seem to fix the first two. Seems like this may be an upstream issue with whatever version of google-gax is getting pulled, but I see nothing in their repo about it.

The same error started happening 9 hours ago in my project that doesn't use firebase at all.

we use these packages

		"@google-cloud/bigquery": "^5.9.3",
		"@google-cloud/firestore": "5.0.1",
		"@google-cloud/functions-framework": "2.1.0",
		"@google-cloud/pubsub": "^2.12.0",
		"@google-cloud/secret-manager": "3.10.1",
		"@google-cloud/storage": "^5.16.1",

Issue happens on build

@dimavedenyapin Thanks for sharing!

It looks like the upstream issue has been fixed. I confirmed locally that a newly initialized TS functions project don't have tsc issue described in the OP.
