Features and Changes

• Adds POST /demo-datasource-project private endpoint, in line with https://www.notion.so/growthbook/Tech-Spec-Sample-Datasource-Creation-42936c77e753476d8be99c0b02c848eb
• Endpoint creates following assets:
  • Project with reliable project ID
  • Datasource to Postgres DB (for now my local, will update to cloud instance)

This seems very fragile

I created a constant name that can be used in both places, and made sure the denominator existed before doing anything with it.

I experienced an issue when pulling this into my code. I'm guessing it won't work unless the datasource exists, and it doesn't.

After the latest SSL change, it works.
