External registry fails

[ashish1099]

+ export 'REGISTRY=***'
+ export 'IMAGE=***/obmondo/dockerfiles/jammy-generic-build'
+ echo refs/pull/5/head
+ sed -E 's/refs\/(heads|tags)\///g'
+ sed -e 's/\//-/g'
+ export 'TAG=1.0.0'
+ export 'TAG=1.0.0'
+ export 'TAG=1.0.0'
+ export 'USERNAME=asdad'
+ export 'PASSWORD=***'

The registry env never gets a real value, not sure why, even when I have give a static string in my workflow.

to test this, did a fork and change directly on the entrypoint script and now it works
I'm not sure where is the problem here.
some help would be nice
