Missing transitive dependency on protobufjs

[maxmil]

When using the library with Yarn 3 (via google-cloud/spanner) module resolution is failing at runtime because protobufjs/minimal is referenced from build/src/generated/ but the transitive dependency on protobufjs is not declared in package json.

Error: grpc-gcp tried to access protobufjs, but it isn't declared in its dependencies; this makes the require call ambiguous and unsound.

Required package: protobufjs (via "protobufjs/minimal")
Required by: grpc-gcp@npm:1.0.1 (via /.yarn/cache/grpc-gcp-npm-1.0.1-d26546ce0e-ad6608b982.zip/node_modules/grpc-gcp/build/src/generated/)

Require stack:
- .yarn/cache/grpc-gcp-npm-1.0.1-d26546ce0e-ad6608b982.zip/node_modules/grpc-gcp/build/src/generated/grpc_gcp.js
- .yarn/cache/grpc-gcp-npm-1.0.1-d26546ce0e-ad6608b982.zip/node_modules/grpc-gcp/build/src/index.js
- .yarn/cache/@google-cloud-spanner-npm-6.11.0-4009155329-6a21287f0f.zip/node_modules/@google-cloud/spanner/build/src/index.js

Environment details

• OS: Debian 12.0
• Node.js version: 18.14.0
• yarn version: 3.6.0
• grpc-gcp version: 1.0.1

Steps to reproduce

1. Create a project with the following package.json

{
"name": "test-spanner-nodejs",
"version": "1.0.0",
"dependencies": {
  "@google-cloud/spanner": "^6.11.0"
},
"packageManager": "yarn@3.6.0"
}

4. yarn install
5. Copy main.js

(async () => {
  const {Spanner} = require('@google-cloud/spanner');
  const spanner = new Spanner({projectId: 'your-project-id'});
  await spanner.instance("your-instance").database("your-database").run("select 1")
})()

7. yarn node main.js

You should see the error above. Adding "protobufjs": "^7.2.3" to the dependencies in package.json fixes the problem.
