Enable "recursive" detection in GCS

[afleisc]

Removing the current directory parameter allows this function to return all SQL files in the bucket rather than only the ones in one directory.

See this link for an example

Ran a test and noticed:

• Recurses folders and can detect the SQL
• will try to parse folder paths as SQL files
• will try to parse any file (e.g. .txt, .png) as a SQL file

A quick fix would be to add a filter for file names with ending with .sql
