Hi Prasads,

You could probably fix this by validating your Access Rules. If there is a Microflow assigned to your button then check whether the correct user roles have access to this Microflow. If the button has a Show page activity assigned to it, check whether the user has rights to access this page.

If this doesn't help, please elaborate more about the functionality of the button. If there is some additional logic within your Microflow, there might be other causes.

Below are the screenshots of modal & console.

Hi prasads aher

It might be a security issue please make sure that the user that you logged in with has access to create and write for the entity that you are passing to the popup if yes

So make sure that you are using a create object in the call action or if you are using a microflow in the call action make sure to create an object and pass it to the popup page

Please recommend this answer as accepted answer if solves the issue

Regards
