Your command is missing a /dev it should be:

sudo dd if=/dev/sda of=/dev/nvme0n1 bs=1b
_______________________^^^^^

The "no space on device" error comes because without the /dev dd is
attempting to write a file called nvme0n1 in / but since / runs out of
space before it finishes the file is never closed and thus no directory
entry is written which is why yuou never see it.

Also I don't think bs=1b is likely to be a good blocksize (1
byte). If the version of dd you're using doesn't support bs=1m then try
bs=1024k or be=1048576. The idea is to get it to use the largest block size
(and thus writes) that the data path will support.
