npx nx-ignore <app> not working on Vercel Build

[seloner]

Current Behavior

I make a change to a shared library our nx environment. The app with name connector uses that shared library. Locally npx nx-ignore connector returns that the build can proceed.

I commit my code to Gitlab and then Vercel starts to automatically build. I added in npx nx-ignore connector in the Vercel settings. However, when this script is triggered in the Vercel build it skips over it and says "The Deployment has been canceled as a result of running the command defined in the "Ignored Build Step" setting

Expected Behavior

I expect it to build because that app was affected as I could see that it was affected locally.

I can confirm I am also experiencing this issue.

I am also experience the same issue. There are two different errors on 2 different projects.

• 1st one having trouble to compare the commit to the ref on main branch
• 2nd one cancelled the build as it determines that the merge not affecting the project

[seloner]

I believe the issue it which root folder you choose. If you choose the root folder of the monorepo in the project of vercel as root it works. But in a vercel project you can choose as root folder a subfolder . So the npx nx-ignore is running in the subfolder instead in top level.

[sigginjals]

I'm only seeing builds showing a false positive. They should be deployed due to a change but aren't.
One reason could be that the project in question is labeled as a "library" but has a storybook deployment attached to it.
This used to work, so not sure what changed.
Edit
Perhaps this line?

I'm also having this problem.
I have a monorepo with Nx and 2 apps are deployed via Vercel.

I've added npx nx-ignore [app-name] to each app and when I'm changing one of them (for instance 'backoffice' app) and push the code to branch I get this error message:

As @seloner mentioned, I have subfolders for the apps, this is how Vercel is working with monorepos.

For instance:

Anyone found a solution for it ?

[seloner]

Try to cd out in the root folder when running npx nx-ignore .
The issue is that you need to run the command in the root folder but because the setup of subfolders the command runs in the sub folder .

[jeniabrook]

@seloner I've tried the following: cd ../.. && npx nx-ignore backoffice.
Monorepo structure:

root
   |
   |---apps
           |
           |---backoffice
           |
   |---packages

Maybe the the command that I'm using is not correct.

fwiw, i think i fixed this problem by manually specifying the workspace root, which for some reason nx-ignore was not figuring out, like so:

npx nx-ignore --root="$(dirname $(dirname $PWD))" --verbose @friends-library/evans

the double dirname is to go up two levels (from where my app was). you could also try hardcoding /vercel/path0 as the root
