As stated in the question, my GetMapping only works when I do not input any parameters. I've also had some weird errors with some PostMapping actions requiring more explicit path declarations in my form action tags.
I don't know what to even reinstall if this is an issue with a faulty installation, I've reinstalled my java and used both eclipse(spring tool suite 4) and visual studio code with no changes in the nature of the errors I'm seeing.
Any help greatly appreciated.
