Xano Test data source API error

I try to use Test data source just adding a header “X-Data-Source: test” in both Xano plugins (Auth & Xano).
I get 500 error “Invalid data source” when trying to create test user (sign up) and login with test user.

Whet does it mean? Is it Weweb side or Xano side?

It means you have to create a Data Source named “test” on your Xano => Data Sources - Xano Documentation

Yep I have created one and I have records there. I will contact Xano team then if this is not weweb issue

Did you used this step to configure your data source ?
