I have some values in my database which can be null if they have not already been entered.
But when I use Thymeleaf in my html, it gives an error when parsing null values.
Is there any way to handle this?

This can also be handled using the elvis operator ?: which will add a default value when the field is null:
<span th:text="${object.property} ?: 'default value'"></span>
Also worth to look at documentation for #objects build-in helper: https://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html#objects
There is useful: ${#objects.nullSafe(obj, default)}
I use
<div th:text ="${variable != null} ? (${variable != ''} ? ${variable} : 'empty string message') : 'null message' "></div>
you can use this solution it is working for me
<span th:text="${#objects.nullSafe(doctor?.cabinet?.name,'')}"></span>
The shortest way! it's working for me, Where NA is my default value.
<td th:text="${ins.eValue!=null}? ${ins.eValue}:'NA'" />
