Cisco DNA Center cannot pull a device's software image directly from the device. Why is the image not uploading?

Cisco DNA Center cannot directly pull a software image from a device if the device is operating in install mode. In install mode, the device's software image is composed of multiple individual files, making it impractical for DNA Center to retrieve a single, consolidated image file for transfer or backup. Instead, DNA Center expects a single, monolithic image file, which is characteristic of bundle mode. Resyncing the device to Cisco DNA Center might resolve certain communication issues but won't change the device's software operating mode. Loss of connectivity would prevent any operations, not specifically image upload. While bundle mode is the preferred state for DNA Center image management, the question states the image is not uploading, and install mode is the reason for this specific failure.
