Comment transférer du contrat à partir de Babylone

J'essaie depasser d'un contrat àpartet de construire latransaction commeexpliqué ici:

 tezos-client transfer 0 from tz1xxx to KT1xxx \
            --entrypoint 'do' \
            --arg '{ DROP ; NIL operation ; PUSH key_hash tz1xxx ; IMPLICIT_ACCOUNT ; PUSH mutez 10000 ; UNIT ; TRANSFER_TOKENS ; CONS }' -D
 

Cependant,je reçois lemessage d'erreur suivant:

 Invalid primitive:
  1: { DROP ;
  2:   NIL operation ;
  3:   PUSH key_hash tz1xxx ;
  4:   IMPLICIT_ACCOUNT ;
  5:   PUSH mutez 10000 ;
  6:   UNIT ;
  7:   TRANSFER_TOKENS ;
  8:   CONS }
Primitive tz1xxx has invalid case.
Fatal error:
  transfer simulation failed
 

Que dois-je changerpour créer unetransaction valide?

I'm trying to transfer from an originated contract and built the transaction as explained here:

tezos-client transfer 0 from tz1xxx to KT1xxx \
            --entrypoint 'do' \
            --arg '{ DROP ; NIL operation ; PUSH key_hash tz1xxx ; IMPLICIT_ACCOUNT ; PUSH mutez 10000 ; UNIT ; TRANSFER_TOKENS ; CONS }' -D

However, I receive the following error message:

Invalid primitive:
  1: { DROP ;
  2:   NIL operation ;
  3:   PUSH key_hash tz1xxx ;
  4:   IMPLICIT_ACCOUNT ;
  5:   PUSH mutez 10000 ;
  6:   UNIT ;
  7:   TRANSFER_TOKENS ;
  8:   CONS }
Primitive tz1xxx has invalid case.
Fatal error:
  transfer simulation failed

What do I need to change to build a valid transaction?
