I am confused about this particular transaction:

{

    }
  ]
}

It seems like the output script is invalid and it contains no output addresses.
Doing a scriptdecode yields:

{
  "asm": "1 ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff 02323c909b017748294c1d1fb82648b2c2905cd941d9a863e036b3157e8aa85dd3 3 OP_CHECKMULTISIG",
  "type": "nonstandard",
  "p2sh": "3Pr9qaUxaHFZbbdojAZFozH34dEqjpe4dU"
}

which normally would be fine, invalid script, value burnt - no problem
However, this output is spent here:

    }
  ],
  "vout": [

        ]
      }
    }
  ]
}

What was the signature used? What is the address that signed for this?

The script is valid, I was assuming that bitcoin core would be the authority.
Script decode:

51  OP_1
4c  Push data
78  Push 120 decimal  = 78 hex bytes
    ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
4c  Push data
78  Push 120 decimal  = 78 hex bytes
    fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
21  Push 33 dec = 21 hex: 
    02323c909b017748294c1d1fb82648b2c2905cd941d9a863e036b3157e8aa85dd3
53  OP_3
ae  OP_CHECKMULTISIG

02323c909b017748294c1d1fb82648b2c2905cd941d9a863e036b3157e8aa85dd3
translates to this base58 address:
1AqLAdfMzfVpdCAtk4rMCUCK6vvNUkGBdm
that can sign for the transaction:
