Error 500 on ajax in chrome extension in ubuntu, why?

Question

ubuntu

In general, I made an extension to chrome. It takes data from the site and sends it to my server via https (it also required to do this, it didn’t want to via http). At the first start, it wrote to the console that my site was somehow bad, I followed the link from the ajax request, chrome notified that the certificate was bad and the site was dangerous, well, I clicked to go anyway. Now it began to write error 500 (Internal Server Error) when the extension is working with ajax requests. As I understand it, all requests are cut from the extension to my site, because if you go over by hand, then everything works out fine. How to make chrome not write these errors but send requests normally?

UPD. Indeed, a server error, I was sure that everything was ok there, it turned out that I forgot that one script was changing and there was an error. I looked at the logs on the server and immediately saw, although if you follow the links, you can’t visually see that the error is returning back.
