Flushing a GPT partition table using dd does not work as the table is duplicated at the end of the disk as well
Use the sgdisk –Z command

I believe the error message says that there is no space left on the device for the second partition to be created. Perhaps try to flush gpt with old good dd.

Perhaps try to zap the disks first?
