If I change extensions\planner.js so it handled args and args.extensions being null...

exports.wantDynamic = wantDynamic;
async function want(args) {
    const instanceSpecs = [];
    const errors = [];
    for (const e of Object.entries(args?.extensions ?? {})) {  # <--- deal with null

the command works.

OK I think I worked out what's going on. I have a function called "externalApi" some code somewhere is assuming that because I have a function that start with "ext" I have extensions installed... then it freaks out when I don't have any and it gets an "undefined" back in args.extensions.

Hey @NigelThorne, thanks for reaching out to us. It looks like the issue you’re encountering is a duplicate of #7575. Currently, you could try downgrading to firebase-tools v13.15.2 to workaround the issue or upgrading to v13.15.4.

Do note however this issue #7582 on v13.15.4 where if don’t have an extension defined in your firebase.json, it would get deleted if you pass the --force flag.
