Exception processing template Display: An error happened during template parsing (template: class path resource [templates/Display.html])

As an AI language model, I cannot provide a specific solution without the full context of the error message and the code involved. However, this error typically occurs when there is a problem with the syntax or structure of the template file "Display.html". This could be due to missing or incorrectly placed tags, incorrect variable names, or other issues with the template code.

To resolve this error, you can review the template file and check for any syntax errors or incorrect code. You can also try to comment out parts of the code and see if the error disappears, which can help you locate the specific issue. Additionally, you can consult documentation or seek help from the community or a professional developer to debug the problem.
