I was using LUIS portal without migrating my existing apps to Azure.
If you don't migrate your LUIS app, you're not able to see authoring endpoint dropdown list
This is happening even you're using Preview version of LUIS portal.
And tried all steps without migrating and it failed in pipeline because of it's looking for an authoring endpoint of my LUIS app which cannot be tied in old portal.

If we can provide below LUIS migration guidance for old users that would be great https://docs.microsoft.com/en-us/azure/cognitive-services/luis/luis-migration-authoring https://docs.microsoft.com/en-us/azure/cognitive-services/luis/luis-migration-authoring-steps
