hf_legic_clone script do not run // attempt to index local 'readbytes' (a nil value)

Hello!

I try to clone a Legic Prime Card to another card using the hf_legic_clone Script.

Unfortunately the script returns an error.

Any Ideas?

Have good day!

the biggest issue with legic for us is that noone has access to the different dumps / reader that is needed to verify the functionality of the script.

So you are the best person to do it!

Okay. What do I have to do? ☺️

debug the script ....
