Property 'fetch' does not exist on type 'Gaxios'. (in v10.1.0)

[stefandoorn]

We are noticing the following error when trying to run tsc on our code-base. It seems to be working fine in previous versions. We use Renovate to update our dependencies and during a regular lock file maintenance run this arises (this is basically an npm update call).

Our dependencies on @google:

    "@google-cloud/bigquery": "^8.0.0",
    "@google-cloud/pubsub": "^5.0.0",
    "@google-cloud/storage": "^7.0.0",

When updating google-auth-library (npm update google-auth-library) the error arises. I think these are relevant in package-lock.json:

Please post a valid reproduction link as I cannot reproduce it locally. Thank you.

[ZeelRavalani]

Here is a simple reproduction repo to recreate the error: https://github.com/ZeelRavalani/Google-Authentication-TypeScript-Error

The issue consistently appears when both @google-cloud/bigquery and @google-cloud/storage are installed. More context and findings are detailed in the README.

[Dan-C-Reed]

@sofisl — Thanks for working on this issue! I was wondering if you have a timeline for when you anticipate issuing a bug fix so that we can plan accordingly? Many thanks in advance!

[stefandoorn]

@sofisl @leahecole Anything we can do to help you out here? I tried understanding what is the exact cause here / underlying package that might cause this, but failed to find it..

[stefandoorn]

Today we ran a npm update again, and some underlying package (don't know which one) seems to have updated it's usage of google-auth-library. Now, we don't see both v9 & v10 being installed anymore, and then the error disappears in our use-case.

[stefandoorn]

Hmmmm - it seems that this was an edge case, not sure why it worked, but we have many where it didn't work. So I might have just looked wrongly on that specific repo.
