Zigbee2MQTT:error 2021-04-02 20:05:08: Failed to check if update available for 'bathroom/light/mirror/switch' (No image available for imageType '0x7b22' with hardware version 6)

Do note a subsequent check fails, as the image type has changes as per the release notes for the firmware.

Migration to ubisys Compact Firmware Upgrade 2.0: CFWU 2.0 is an encrypted, signed and compressed OTA file format. This improves security, cuts update time per device in half with positive effects on battery life for battery powered devices and reduced network bandwidth utilization, and increases available space on the device for future upgrades and new features. We are making all ubisys devices ready for the next major Zigbee release with lots of new features – stay tuned
Migration is a one-way process and devices will have a different OTA image type after the upgrade. The new image type is 0x7b22
