1. Is this a client library issue or a product issue?
   A client library issue.

2. Did someone already solve this?
   No.

3. Do you have a support contract?
   No.

Environment details

• OS: Ubuntu
• Node.js version: 18.17.1
• npm version: 9.6.7
• @google-cloud/bigquery version: 7.2.0

Steps to reproduce

1. Use createInputStream to create an input stream.
2. Send rows through the stream until an TypeError: Cannot read properties of undefined (reading 'insertErrors') occurs.

Do you have some scenario that this happens ? Would be nice to add some tests to the PR #1273

I didn't dig into it too much to be honest. It seems to happen the most when we have multiple services all inserting to the same table at the same time and is hard to reproduce from just a single machine.

Here is the stack trace that we see in the logs:

I also see: request to https://www.googleapis.com/oauth2/v4/token failed, reason: Client network socket disconnected before secure TLS connection was established on nearby lines, so maybe that's the root error that fails to provide a resp object as expected?
