issue with deploying model over vertex ai pipeline challenge : gsp354

i have been trying to deploy the model for couple of times which many alterations but every time it fails at the same step ;
tried to create a new service account and enable all necessary permissions for vertex ai pipelines to deploy the model , no success yet , although i was able to succeed at creating the endpoint every time without issues
tried with minimal deployment configuration and same requirements as the local run yet still no success

link to the challenge lab is here -> https://www.cloudskillsboost.google/focuses/22019?parent=catalog

scrapped through old issues to find out there was a similar issue reported and patched it here -> https://github.com/GoogleCloudPlatform/training-data-analyst/pull/2250

can anyone please check and let us know if the challenge lab is working fine ?

Start with the linked GSP354 challenge lab and compare the deployment failure with the previously related pull request #2250. Reproduce the failing deployment step and determine whether the lab still exhibits the reported behavior; done means the failure is confirmed or its cause is documented.
