Artifact deployment failed in RPi

Hi,
I’m new to Mender, so I might ask some basic questions. For exploring Mender, I converted a raw image into Mender client. Then copied the image file into another SD card and added a new directory and file in home/pi/ as a marker. Then converted this image file and used the (.mender) file i-e: Artifact to update the client. Uploaded the Artifact in releases tab, then created deployment. My deployment fails by giving this error:

> 2020-07-10 09:35:26 +0000 UTC error: transient error: Reboot to new update failed. Expected “upgrade_available” flag to be true but it was false
I searched for this issue but couldn’t find it. Your help is appreciated.
My deployment log:
