Summary
Sanity.external docker file appears to require a syntax fix.

Next steps
This should be assigned to the POC for external testing so they can fix it. Will add a comment in Slack.

@LongyuZhang - are you running with an additional parameter being set that we are not using in our EA-triggered pipelines on ci.adoptium.net, or is FUNCTIONAL_TEST_TAG supposed to be set from testenv.properties file (even if we are not setting USE_TESTENV_PROPERTIES=true ?

[LongyuZhang]

It seems to be related to branch setting through sanitize_test_names to set the tag (link), will look into it.

The ADOPTOPENJDK_SHA used in this test is 7e3811b9d4c6fcf265d2fc7e9852412034fe6260 which is two weeks ago. The tag problem has been fixed by PR later than it #5406.
