I have a very strange problem in my project. Let me explain that my project is based on HTML, Extjs and JSON. When the page loads in the browser, the header information of the jquery file is added dynamically. I have no idea how to add this information to it. Because of this, the application did not load. Similarly, in some JSON files, this HTTP information is added dynamically, which also causes the loading of JSON files to fail. I get an error in the browser console, when I click on this error message, I need to see this HTTP information. 
Previously, the project worked fine, the last few days I ran into this problem. I am attaching a screenshot from a jquery file.
