Hello Team,
We have blazer 7 application, deployed in Web App, which us using auth0 authentication , but within this application lot of different api’s(writtern in blazzer 8.0 as durable trigger deployed in function app) called to perform some random data operation.
We are able to login to UI using auth0 but when calling api by authorizing using auth0, we are getting below error,
has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. If an opaque response serves your needs, set the request’s mode to ‘no-cors’ to fetch the resource with CORS disabled."
We have added all setting in auth0 and web app for CORS with all possible URL.

Please suggest if anything.

Thanks in advance
