unable to find user root: invalid argument | Dagger | Page 1

#

when I launch my action with dagger, I get this error and I don't know how to fix it. If anyone has already encountered this error, I've updated my version of dagger but the problem persists.

@drowsy stream does your pipeline use WithUser by any chance?

drowsy stream Nov 27, 2024, 2:19 PM

#

yes, i use withUser("root")

#

when I try any command withExec I automatically get this error, even a “whoami” returns this error

#

in that case it's very likely that the base image you're running your witUser from doesn't have the user root?

#

yes i use this image ghcr.io/cirruslabs/flutter:3.7.7

I think the problem comes from the mapping between docker and dagger

#

I don't know how to resolve it

are you able to share any of your code? or a minimal repro?

i'm a real beginner in dagger and my code isn't very clean sorry 😅

Looks fine to me 🙂 Does it behave the same without the withUser("root")? Just wondering because root is already the default for the container. I don't know how that would make a difference though

#

yes, I get this error even without withUser(“root”), this action doesn't change anything, i think my setup of dagger isn't correct but i follow the installation page

#

ok so this was kind of a sneaky error 😂 Change the .withMountedDirectory("./", src) to .withMountedDirectory("/src", src). Since you're setting the withWorkdir after that command, it's actually applying the input directory to / which I think is basically wiping the original filesystem

#

your pipeline has terminated, I no longer have the root error but it doesn't want to run my cat and I have no further details apart from that,

#

Thank you very much for your time.

should the path for that command be > company/android/local.properties? (missing company)?
