您好，我在运行您的代码是遇到如下问题：
[17:53:09] - Core.provider.extract_pdf_info - ERROR - Error: The number of items in middle_json (311) does not match the number of content items (417).
[17:53:09] - main - ERROR - - ERROR: Failed to build index. Reason: The number of items in middle_json (311) does not match the number of content items (417).
虽然是简单的长度不匹配问题，但还是让我很疑惑，想问一下您是否有解决办法
