proposing MSIG throws "Failed with error: Bad Cast"

[heifner]

cleos leap v3.1.x works. cleos version: v2.1.0 is not supported, but cleos leap main branch has a similar issue as cleos version: v2.1.0 as it modifies the JSON in a similar way as v2.1.0.

The eosio.msig contract ABI expects the transaction "data" as a hex string.

    "structs": [{
        "name": "action",
        "base": "",
        "fields": [{
            "name": "account",
            "type": "name"
          },{
            "name": "name",
            "type": "name"
          },{
            "name": "authorization",
            "type": "permission_level[]"
          },{
            "name": "data",
            "type": "bytes"
          }
        ]
      }

cleos leap v3.1.x produces a transfer.json in the correct format.

{
  "expiration": "2022-11-11T10:24:24",
  "ref_block_num": 41363,
  "ref_block_prefix": 937202845,
  "max_net_usage_words": 0,
  "max_cpu_usage_ms": 0,
  "delay_sec": 0,
  "context_free_actions": [],
  "actions": [{
      "account": "eosio.token",
      "name": "transfer",
      "authorization": [{
          "actor": "eosio",
          "permission": "active"
        }
      ],
      "data": "0000000000ea305500408c7a02ea3055102700000000000004454f53000000000f70726f706f7365206173204d534947"
    }
  ],
  "transaction_extensions": [],
  "signatures": [],
  "context_free_data": []
}

cleos leap main branch expands the "data" section providing an unexpected "data" section.

{
  "expiration": "2022-11-11T09:57:49",
  "ref_block_num": 38171,
  "ref_block_prefix": 3147693954,
  "max_net_usage_words": 0,
  "max_cpu_usage_ms": 0,
  "delay_sec": 0,
  "context_free_actions": [],
  "actions": [{
      "account": "eosio.token",
      "name": "transfer",
      "authorization": [{
          "actor": "eosio",
          "permission": "active"
        }
      ],
      "data": {
        "from": "eosio",
        "to": "eosio.null",
        "quantity": "1.0000 EOS",
        "memo": "propose as MSIG"
      },
      "hex_data": "0000000000ea305500408c7a02ea3055102700000000000004454f53000000000f70726f706f7365206173204d534947"
    }
  ],
  "transaction_extensions": [],
  "signatures": [],
  "context_free_data": []
}

Removing the "data" section is not the correct approach as that will generate an empty action which will fail to execute.

[heifner]

The work-around is to remove the "data" section and rename "hex_data" to "data".
If using cleos v2.1.x, also will need to add "transaction_extensions": [], to the generated transaction JSON.
