Why do I encounter a 0 code error when uploading function packs?

The primary reason for this issue is that your file likely exceeds the maximum allowed file size of 10MB. Currently, the system only supports uploads up to this limit, and files larger than this will result in an upload error. To resolve this, consider compressing your file to reduce its size, then attempt the upload again. Additionally, please ensure your file is in a supported format, such as PDF or JPEG.
