AWS Volume Error Invalid value 'instancenumber' for instanceId. Instance does not have a volume attached at root (/dev/sda1)

Error,

Attaching an instance to a volume and getting this error.

Invalid value 'i-instane number' for instanceId. Instance does not have a volume attached at root (/dev/sda1)

Solution:

by default when you attache a volume you get "/dev/sdf"  value in "Device" column

update "Device" value to  "/dev/sda1"

and start the instance. it will work.
