thymeleaf parsing template issues, the path fails to get recognized-CodePudding

I have 2 Root Cause Issues/Errors

org.attoparser.ParseException: Error resolving template [components/folder-list], template might not exist or might not be accessible by any of the configured Template Resolvers (template: "inbox-page" - line 65, col 14)

org.thymeleaf.exceptions.TemplateInputException: Error resolving template [components/folder-list], template might not exist or might not be accessible by any of the configured Template Resolvers (template: "inbox-page" - line 65, col 14)

The bug arised when I converted some .html code and attempted to extract it as a component.
I tried different paths from absolute path to package path; path fails to get recognized regardless.

OLD CODE

templates/inbox-page.html old but works.
If we swap the new inbox-page.html with this old code, it will work but what I want is to convert it as a component.

Move your components folder inside of templates. Thymeleaf searches everything relative to templates.
