#5689 [Housekeeping] Improve ImageSpec error message on wrong registry format Issue created by davidmirror-ops Describe the issue When, by mistake, I use an incorrectly formatted registry in the ImageSpec config:

base_image="<http://ghcr.io/flyteorg/flytekit:py3.9-latest|ghcr.io/flyteorg/flytekit:py3.9-latest>",
    packages=["scikit-learn"],
    registry="<http://ghcr.io/davidmirror-ops/flyte-scklearn:latest|ghcr.io/davidmirror-ops/flyte-scklearn:latest>", 
)

Instead of failing,

pyflyte run

throws a misleading message and proceeds with execution:

Image <http://ghcr.io/davidmirror-ops/flyte-sklearn:latest/flytekit:QDS_o1_Z2WBpkL_QFfWuYw|ghcr.io/davidmirror-ops/flyte-sklearn:latest/flytekit:QDS_o1_Z2WBpkL_QFfWuYw> found. Skip building.

Of course the image is not there in the registry, so not sure why it says

found

What if we do not do this? New users could spend cycles troubleshooting this. It's important to note that the console gives a better error message, one that actually points to the problem:

|Failed to apply default image tag "<http://ghcr.io/davidmirror-ops/flyte-sklearn:latest/flytekit:iF_UE5oVrp6HRxnCSINhEg|ghcr.io/davidmirror-ops/flyte-sklearn:latest/flytekit:iF_UE5oVrp6HRxnCSINhEg>": couldn't parse image name "<http://ghcr.io/davidmirror-ops/flyte-sklearn:latest/flytekit:iF_UE5oVrp6HRxnCSINhEg|ghcr.io/davidmirror-ops/flyte-sklearn:latest/flytekit:iF_UE5oVrp6HRxnCSINhEg>": invalid reference format
