Firebase Functions for Firestore Failing due to NanoMatch Issue

Question

I am new to cloud functions and was testing this sample code https://github.com/firebase/functions-samples/tree/master/quickstarts/uppercase-firestore This fails to execute due to an error from nanomatch. Looking at nanomatch repository on GitHub This is a listed issue and reverting back to 1.2.9 takes care of this error.

I am trying to fix this on my end - but how do I do this? Can somebody guide me on this. Thank you for the help.

Answer 1

THIS BUG WAS FIXED

The version that caused the bug was reverted right when this issue was reported on GitHub, which was within minutes of it being released. To get the fix, just reinstall. You might need to delete node_modules and/or lockfiles first, to ensure cached versions aren't used by NPM. This conversation belongs on GitHub, so that we can respond to user feedback. I found this by chance. StackOverflow is not for support).

Edit 2: it appears that firebase-admin itself needs to re-install dependencies as well. I'm looking into how to make that happen.

Please report and check issues on GitHub, where the codebase is and where this discussion belongs.
