Then i imported (or require) the CORS in my index file Well in my case i deployed my back-end in Heroku, and the front-end in Netlify, Until this stage everything looks good the front end deployment and the back-end deployment don't response with any errors, But when i tried to send a message in the chatroom i couldn't when i inspect in the browser i got this errorĪfter hours of searching and reading about CORS i managed to solve this error and make my chat works, First thing i did In this context, 'other origins' means the URL being accessed differs from the location that the JavaScript is running from, by having: Most of the time, A script running in the user's browser would only ever need to access resources on the same origin, So the fact that JavaScript can't normally access resources on other origins is a good thing for security. Everything works fine when you test your REST calls with curl,But when you implement them in the UI, It does not,It’s probably the mysterious CORS mechanism blocking you,So if you right click, select Inspect, and go to Console tab, and then you will see an error. Let's first give you an idea about CORS, Well when you're building an UI ,You need to connect to remote API to get or send some data.

Im guessing that in order to make it work on Azure we should have Access-Control-Allow-Origin: * when calling rasa on We don’t have the mention of CORS configuration in our logs and a far as I remember we never had one. When calling to Azure deployed rasa ( ) we have no Access-Control-Allow-Origin header and the error: Access to XMLHttpRequest at '' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. To clarify, when calling rasa with Webchat on local system ( we have a null header: We are running rasa with the command: run -m models -enable-api -cors '*' -debug Im trying to deploy the rasa docker image into our Azure plateform.
