I am trying to create a registration form. For this I use html in conjunction with thymeleaf. For some reason, after making the necessary fragments of thymeleaf in html, part of the page with the actual form has ceased to appear. It seems to do everything on the tutorial. Googled a lot, found a bunch of options to improve my code in other places, but I didn’t attack the solution of my question. Please help resolve the issue. When I open the "view code" on the open page, I see that the panel displays an error message - "Failed to load resource: the server responded with a status of 500 ()". I understand the problem may lie in the server part. Although I have no idea what could be wrong there. My spring controller just displays the view on the screen. There is no action inside. Below is an excerpt of my code. Please tell me what I am missing and where you can see. Google a lot, but did not find the answer.
