Cannot read properties of undefined (reading 'indexOf')

[justaguyin2k23]

protobuf.js version: 7.2.5
gprc-js version 1.9.13
proto-loader version 0.7.10

line #488 of [protobuf.js/ext/descriptor/index.js]

if ((descriptor.oneofIndex = this.parent.oneofsArray.indexOf(this.partOf)) < 0)
        throw Error("missing oneof");

causes the error Cannot read properties of undefined (reading 'indexOf') when calling proto-loader's loadSync function.

const grpc = require('@grpc/grpc-js');
const protoLoader = require('@grpc/proto-loader');
const pathLib = require('path');
const proto_path = [
  pathLib.join(__dirname,'./protos/dummy_service.proto')
];
 const packageDefinition = protoLoader.loadSync(protopath);

This specifically happens when the latest version of buf/validate.proto is among the proto files being used.

Changing line #488 to below solves the issue,

if ((this.parent.oneofsArray && descriptor.oneofIndex = this.parent.oneofsArray.indexOf(this.partOf)) < 0)

I see a somewhat similar issue, #1898 but no resolution.
