Currently using my account and the command dbutils.notebook.entry_point.getDbutils().notebook().getContext().apiUrl().get().apiToken().get() to get my current databricks token to access this function.  And my user just doesn't have admin permissions over the workspace. 
It doesn't seem to be a role/permission issue. I'm able to access other PublicPreview features (like LLM RAG with vector search), just this foundation model training in particular is causing trouble.
