ydotool inserts digits instead of keys

ydotool key 29:1 56:1 59:1 59:0 56:0 29:0; sleep 2; ydotool type 'echo Hey guys. This is Austin.'

ydotool: notice: ydotoold backend unavailable (may have latency+delay issues)
255552ydotool: notice: ydotoold backend unavailable (may have latency+delay issues)
echo Hey guys. This is Austin.emoxam@emoxam-b450mds3h:~/Downloads$ 255552echo Hey guys. This is Austin.

Why it echoes 255552 ?
