Google Ads is no longer supporting AdWords API in favor of Google Ads API.
Although both APIs share similar functionality the new API is breaking a lot of the older unmaintained scripts mainly due to the schema changes.
e.g. Keywords Performance Report is now keyword_view
The scripts for now have essentially been converted from AWQL (AdWords Query Language) to GAQL (Google Ads Query Language)
Let me know if you run into any issues.
