Spring JPA solution to Thymeleaf returning Strings instead of List<Object>

I have created a Thymeleaf form and am attempting to map a field with multiple inputs to a List in a OneToMany entity. However, I keep getting the below error:

default message [Failed to convert property value of type 'java.lang.String' to required type 'project.model.Prop' for property 'propList[0]'; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'java.lang.String' to required type 'project.model.Prop' for property 'propList[0]': no matching editors or conversion strategy found]

Many others on this site have faced a similar error, and I have found someone facing an almost identical issue here. However, for that post, one answer provides a non-JPA solution. At the same time, the answer says that there is a JPA way to handle the issue, but no additional details are provided.

Can anyone explain how to resolve that post's situation with JPA?

If you want to solve the issue with the Spring Data JPA, you must bring the List<Prop> List-object from its repository. Then, you would not need to make your own custom converter to solve the issue.
