9 hours ago To resolve the NullPointerException caused by unchecked checkboxes for "Include Metadata" and "Allow Duplicates" in the /split-pdf-by-chapters feature, you should ensure that the backend receives boolean false instead of null. This can be achieved by setting default values for these fields in the SplitPdfByChaptersRequest class. Here's how you can modify the class:
@Data
@EqualsAndHashCode
@NoArgsConstructor
@AllArgsConstructor
class SplitPdfByChaptersRequest {
private MultipartFile fileInput;
private Integer bookmarkLevel;
private boolean includeMetadata = false; // Default to false
private boolean allowDuplicates = false; // Default to false
}By setting default values for includeMetadata and allowDuplicates to false, the backend will receive false when the checkboxes are unchecked, preventing the NullPointerException [1]. Additionally, ensure that the frontend form is correctly configured to send false when these checkboxes are unchecked [2].

The Problem
Description:
Currently, in the /split-pdf-by-chapters feature, the includeMetadata and allowDuplicates checkboxes are not correctly submitting true or false values based on the user's selection. When the checkboxes are left unchecked, the backend receives null instead of a boolean false, which results in a NullPointerException.
Feature URL: https://stirlingpdf.io/split-pdf-by-chapters
Steps to Reproduce:
Expected Behavior:
The backend should receive true if the checkbox is checked and false if it’s unchecked. The form should correctly handle boolean values for these checkboxes without causing errors.
