Looks like the image info file is not making it through to the tests. There should be lots of --path arguments passed here: https://dev.azure.com/dnceng-public/public/_build/results?buildId=940112&view=logs&j=fc59f0f2-c1bd-58ae-b870-833d1e8a924c&t=42b16712-47b7-5d4e-b8e4-5c4616c57a47&l=51

Image info file is not supposed to be set. That gets set here:

dotnet-docker/eng/common/templates/steps/test-images-linux-client.yml

Lines 24 to 29 in f528525

	if [ "${{ variables['System.TeamProject'] }}" == "${{ parameters.internalProjectName }}" ] && [ "${{ variables['Build.Reason'] }}" != "PullRequest" ]; then
	additionalTestArgs="$additionalTestArgs -PullImages -Registry $(acr-staging.server) -RepoPrefix $(stagingRepoPrefix) -ImageInfoPath $(artifactsPath)/image-info.json"
	if [ "$TESTCATEGORIESOVERRIDE" != "" ]; then
	additionalTestArgs="$additionalTestArgs -TestCategories $TESTCATEGORIESOVERRIDE"
	fi
	fi

It would only happen on internal builds.

And the paths are being set here: https://dev.azure.com/dnceng-public/public/_build/results?buildId=940112&view=logs&j=fc59f0f2-c1bd-58ae-b870-833d1e8a924c&t=42b16712-47b7-5d4e-b8e4-5c4616c57a47&l=12
