@natalieparellano I've changed validation to warning, and build process continues, but now there is error on next step.
I am new to pack and it would be great if someone familiar with the project would assist me

After change I tried to executed command mentioned in issue got nil pointer dereference

./out/pack build stack-validation --builder paketobuildpacks/builder-jammy-base --run-image gcr.io/buildpacks/builder/php:latest

@pglushko thanks for making the changes. I think we now need to update the acceptance test here:

pack/acceptance/acceptance_test.go

Line 1823 in 12b7d24

when("the run image has the wrong stack ID", func() {

to expect a warning instead of a failure.
