Error: Cannot read properties of undefined (reading 'length') when running any capacitor command

[vrxj81]

Whenever running any Capacitor related command, I get this output:

nx run ggs-mobile:copy:ios

> nx run ggs-mobile:copy:ios

Cannot read properties of undefined (reading 'length')

 ———————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————

 >  NX   Ran target copy for project ggs-mobile (328ms)

         With additional flags:

    ✖    1/1 failed
    ✔    0/1 succeeded [0 read from cache]

   See Nx Cloud run details at https://nx.app/runs/XXXXXXXXXX

No idea how to debug this

Seconding this, started getting this error after updating to nx 14:

    "firebase": {
      "executor": "@nxtend/firebase:firebase",
    },

> nx run solui:firebase --cmd="deploy -P staging --token=*******************************************************************************************************"

Cannot read properties of undefined (reading 'length')

"@angular/core": "14.0.1",
"@nrwl/workspace": "14.3.1",
"@nxtend/firebase": "12.1.0",
"firebase": "9.8.3",

Thanks for confirming my suspicion. It worked with NX 14.1, but not with 14.3.

Is there a transparency on the status of supporting NX 14?

This commit seems to be the culprit. They are adding __unparsed__ as a required parameter to run-commands.

See dummy pull request below

For now, reverting to nx 14.2.x solves this issue. I've also opened an issue in nx: https://github.com/nrwl/nx/issues/10750

[dolphinigle]

Nx has fixed this

[VictorienTardif]

Nx has fixed this

Nope :( I upgraded Nx to 14.3.5, the __unparsed__ bug may be fixed but not the Cannot read properties of undefined (reading 'length') one.

I don't think it's related.

Apparently this was fixed in PR https://github.com/nrwl/nx/pull/10753 and then reverted in commit https://github.com/nrwl/nx/commit/d68b9bbc9094829adcc9431bdcf0c5e08980a83a

Is anyone working on a fix? Tried every version since 14 and none worked.

You can use this patch here. Git, pnpm@7.4 (below) and yarn supports patching node modules.

  "pnpm": {
    "patchedDependencies": {

These plugins are moving over to the Nxext repo, and an Nx 14 version has been released. There are some migration guides on their docs site, here's a link to the Ionic Angular guide: https://nxext.dev/docs/ionic-angular/migrating-from-nxtend.html

[cangomescisco]

@devinshoemaker Thanks! :)

[f1ght4fun]

It is still present in the NX15 version ... Is there really a chance to fix this as builds are failing with this issue since Nx14 version ?
