Overriding the default CORS settings
Suppose the page you are debugging requests a resource which is protected against access for security reasons through CORS settings, see https://developer.mozilla.org/en-US/docs/HTTP/Access_control_CORS. You can enable access to the resources protected by default by changing the Chrome extension options.
To override the default CORS settings:
- Right-click and choose Options on the context menu. A web page with Chrome extension options opens showing the parameters to connect to CLion.
In the Force CORS text box, type the pattern that defines the URL addresses you want to make accessible, for example:
During a debugging session, the Chrome extension listens to the port of the JetBrains IDE from which the extension was invoked. Each IDE including CLion has its own default port on which it starts by default.
If for some reason the default CLion port is already busy, CLion finds the closest available port and starts on it. This results in a conflict: CLion is running on a "new" port while the Chrome extension still listens to the port of a previously started product and fails to establish connection with CLion. The conflict reveals when you initiate a debugging session from CLion: the extension fails to connect through the default port, CLion waits for connection from the extension and displays the following message with the port number where it is actually running:
To fix the problem, specify the actual CLion port in the Chrome extension options:
- Right-click and choose Options on the context menu. A web page with the Chrome extension options opens showing the parameters to connect to CLion.
- In the IDE Connection area, specify the actual CLion port in the Port spin box.
