Both of you missed the sentence "Databricks needs to update the definition of the generated profiles file."
The warning is regarding the structure of the profiles.yml which is generated by Databrick. This is not anything I as a user can change accept follow the guide to run with a custom profile which I do not have a need for.
So I wand to reach somebody working at Databricks and can give this information to the team that works on the dbt task.
