Uncaught DOMException: The operation is insecure. error while integration.

[pradeepds]

I'm attempting to integrate the Lightstreamer stock grid using JavaScript. I've followed all the necessary steps, but I encountered the following error in my code: 'Uncaught DOMException: The operation is insecure' in the 'lightstreamer.min.js' file. Could you please provide me with a solution? I'm new to this and would appreciate your guidance."

The error message you're encountering, "Uncaught DOMException: The operation is insecure," is a security feature implemented by browsers. It usually occurs when you're trying to perform an operation that violates the same-origin policy.

Please could you expand a little more about your case?
Maybe some snippets of your code or the full stack trace of the exception.

Regards,
Giuseppe

Can you explain how to reproduce the error above?
If I run the grid demo in my browser, there is no error.
