Summary

Requests are blocked between 2 hosts because of CORS

To fix this , in AlmaLinux9, add in /etc/httpd/sites-enabled/{your-host.conf} inside <VirtualHost> this line:
Header set Access-Control-Allow-Origin "*" - this will allow any origin and you can replace * with your host you you want a specific host, then restart the server

Access to fetch at 'http://social-learning.localhost/import/institutions/3668cc36-31b9-4107-9b6d-7eabfa951cfe' from origin 'http://sl-admin.localhost' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains multiple values 'http://sl-admin.localhost, *', but only one is allowed. Have the server send the header with a valid value, or, if an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
