AND bitwise operation using hexadecimal key issue

**Describe the bug**
When using the following recipe: https://gchq.github.io/CyberChef/#recipe=From_Decimal('Space',false)To_Binary('Space',8)AND(%7B'option':'Hex','string':'0F'%7D)From_Binary('Space',8)&input=MjU1&oeol=VT
the result should be 15 but "Data is not a valid byteArray: [null]" is displayed.

Same with: https://gchq.github.io/CyberChef/#recipe=From_Decimal('Space',false)To_Binary('Space',8)AND(%7B'option':'Binary','string':'00001111'%7D)From_Binary('Space',8)&input=MjU1&oeol=VT

Is there an issue or am I doing something wrong 🤔 ?

Start by replaying the two linked CyberChef recipes with input 255 and compare the hexadecimal and binary AND variants. Trace the AND operation and the following From_Binary step to identify where the invalid byteArray is produced; done means both recipes produce 15 without the error.
