Can't import disk image to Google Cloud Platform

I'm trying to import image to Google Cloud Platform from vmdk file:

gcloud compute images import jira-vmdk --source-file gs://r-vm/jira_0-flat.vmdk.gz --os debian-9

OS pre-verified by import_precheck utility:

import_precheck screen

But an error appears during import:

 How can I fix it? Any ideas?

Problem solved.

The bootloader on the boot disk must not have quiet, rhgb, or splashimage= kernel command line arguments. Compute Engine does not support splash screens on boot. You can remove these values from the GRUB config during the bootloader configuration step.

steps for Debian 9

in /etc/default/grub

comment out

#GRUB_CMDLINE_LINUX_DEFAULT="quiet"

add

GRUB_CMDLINE_LINUX_DEFAULT="console=ttyS0,38400n8d"

sudo update-grub
