Today, I tried Rasa Playground for the first time. I clicked the ‘Train’ button without modifying the given example, but I did not receive a reasonable response. The Playground kept on ‘Training’.
In the console, I found the error message: ‘Reason: CORS request did not succeed.’ Cross-Origin Resource Sharing (CORS) blocked the request: The Same-Origin Policy prevents reading the external resource at https://trainer-service.prototyping.rasa.com/trainings. (Reason: CORS request failed). Status code: (null).
Do you have any ideas? Do I need to change some browser configurations or something similar?
