Failed to convert property value of type javalangString to required type javatimeLocalDate for property startDate; nested exception is orgspringframeworkcoreconvertConversionFailedException Failed to

This error occurs when Spring is unable to convert a string value to a LocalDate object. In this case, the string value '2023-04-04' cannot be converted to a LocalDate object.

To resolve this error, you can modify the code to ensure that the string value is converted to a LocalDate object before it is used in the application. One way to do this is to use the LocalDate.parse() method in Java, which can be used to convert a string value to a LocalDate object.

For example, if the property 'startDate' is defined as a LocalDate object in the application, you can modify the code to use the LocalDate.parse() method to convert the string value to a LocalDate object as follows:

startDate = LocalDate.parse("2023-04-04");

This will ensure that the string value is converted to a LocalDate object before it is used in the application, and should resolve the error.
