Sale cannot be executed in Kadena Pact Marmalde

Question

Errors occur in the following conditions.

Running on local server (ubuntu on windows).

I deployed these files.

Token is minted.

The yaml file is generated via Django. The generated file is then used to run the API request formatter to generate Json.

Template:

code:
  (marmalade.ledger.sale
    (read-msg 'token-id)
    (read-msg 'account)
    (read-decimal 'amount)
    (read-integer 'timeout)
  )
data:
  token-id: "${token_id}"
  account: "${account}"
  amount: ${amount}
  timeout: ${timeout}
  quote:
    price: "${price}"
    recipient-guard:
      keys:
        [ "${recipient_key}", ]
    recipient: ${recipient}

keyPairs:
  - public: ${marmalade_pub}
    secret: ${marmalade_sec}
    caps:
      - name: "marmalade.ledger.SALE"
        args: ["${token_id}", "${account}", ${amount}, ${timeout}]

Generated File：

code:
  (marmalade.ledger.sale
    (read-msg 'token-id)
    (read-msg 'account)
    (read-decimal 'amount)
    (read-integer 'timeout)
  )

  amount: 1.0
  timeout: 100
  quote:
    price: "1.0"

The following error occurred when I posted the Json data to request.post on 'localhost:8080/api/v1/poll'.

{'cD5gqQVmRj08xqOdqfKwLLL2eb76_j_eZDdzV4Xdkjg': {'gas': 0, 'result': {'status': 'failure', 'error': {'callStack': [], 'type': 'EvalError', 'message': 'Managed capability not installed: (marmalade.ledger.OFFER "92496e13-4414-4c58-aceb-0c7d77120af2" "a0fc037522ae0202052775f773e3cf823e3bd7640a12e80694b2dd76" 1.0 100)', 'info': ''}}, 'reqKey': 'cD5gqQVmRj08xqOdqfKwLLL2eb76_j_eZDdzV4Xdkjg', 'logs': None, 'metaData': None, 'continuation': None, 'txId': None}}

How do I get these to work properly?

P.S. I am Japanese and not an English speaker. I used a translation site to ask this question. Sorry if the description is missing.

problem in your request is that you don't installed marmalade.ledger.OFFER capability correctly, timeout in marmalade.ledger.OFFER must be an object with datatype and value. for example { int: 999999 }

1. first of all change your timeout input form 100 to { int: 100 }.

2. you may have to add coin.GAS capability too, otherwise it will give gas error (if your code work without it then it's fine)

3. also you may missing fungible description in data.quote that will give error also. if it give error about fungible description then add blew code in data.quote, after price

fungible: {
    refName: {
        name: "coin",
        namespace: null,
    },
    refSpec: [
        {
            name: "fungible-v2",
            namespace: null,
        },
    ],
},
