Error: Upgrading from 1st Gen to 2nd Gen is not yet supported. See before migrating to 2nd Gen.

We'd like to be able to fallback to deploying as a V1 function. How do we do that?

Searching seems to imply that it might be a node/firebase/firebase-functions version issue.

Also we see messages about URL errors. See below.

• @dougstevenson I will edit the question but that is part of the root of the issue is that it works locally with the firebase local development environment. The error messages are on the cloud environment. And it gives hundreds and hundreds of lines of errors. Thanks. – Ralph Yozzo Commented yesterday
• Could you edit the question to include what you just said, along with more details about your observations? Burying information in comments isn't ideal. Full steps to repro your observations the issue is ideal. See: stackoverflow.com/help/minimal-reproducible-example – Doug Stevenson Commented yesterday
• Without package.json this isn't too reproducible, while everything hints for different nodeJS versions. The expected question format would indeed be: the code which produces the problem + relevant log entries or stack trace. – Martin Zeitler Commented yesterday

1 Answer 1

In order to migrate to v2, you might want to upgrade the local nodeJS version first. Running different nodeJS versions locally and remotely tends to be problematic. The local environment should match the remote environment as close as possible, when using nodeJS or PHP runtime. For example: When setting "engines": {"node": "20"}, one should also run NodeJS 20 locally.

When upgrading the deployment from v1 to v2 isn't possible, you might have to delete the function, which makes it inaccessible for a short period of time. When no or only little traffic is hitting the function, nothing speaks against doing just that.

But when traffic is hitting the function, the most seamless migration strategy might still be: To deploy v2 with another function name, then push a new version of the client. And after some time, one can remove the v1 function. This scenario is basically also described in the documentation.

All the v2 quickstarts use NodeJS 22 and a later version of firebase-admin.
