Chainlink 节点 - encode_tx 错误长度不正确

Question

我正在开发一个外部适配器，但当我向我的本地 chainlink 节点发出请求时它不工作。我在 encode_tx 步骤中遇到此错误。

这是错误：ETHABIEncode: while converting argument 'data' from <nil> to bytes32: incorrect length: expected 32, got 32: bad input for task: bad input for task

这是工作规范：

type = "directrequest"
schemaVersion = 1
name = "eth-lottery-job-test4"
contractAddress = "0x1Cc100f9c198d9CD3410263D4Df7FA7C5C30E34F"
maxTaskDuration = "0s"
observationSource = """
    decode_log   [type="ethabidecodelog"
                  abi="OracleRequest(bytes32 indexed specId, address requester, bytes32 requestId, uint256 payment, address callbackAddr, bytes4 callbackFunctionId, uint256 cancelExpiration, uint256 dataVersion, bytes data)"
                  data="$(jobRun.logData)"
                  topics="$(jobRun.logTopics)"]

    decode_cbor  [type="cborparse" data="$(decode_log.data)"]
    fetch        [type="bridge" name="eth-lottery-test" requestData="{\"id\":$(jobSpec.externalJobID), \"data\": {\"username\":$(decode_cbor.username), \"password\":$(decode_cbor.password), \"winner_ticket\":$(decode_cbor.winner_ticket), \"tickets\":$(decode_cbor.tickets)}}"]
    parse        [type="jsonparse" path="data,winners" data="$(fetch)"]
    encode_data  [type="ethabiencode" abi="(uint256[] winners)" data="{ \"winners\": $(parse) }"]
    encode_tx    [type="ethabiencode"
                  abi="fulfillOracleRequest(bytes32 requestId, uint256 payment, address callbackAddress, bytes4 callbackFunctionId, uint256 expiration, bytes32 data)"
                  data="{\"requestId\": $(decode_log.requestId), \"payment\": $(decode_log.payment), \"callbackAddress\": $(decode_log.callbackAddr), \"callbackFunctionId\": $(decode_log.callbackFunctionId), \"expiration\": $(decode_log.cancelExpiration), \"data\": $(encode_data)}"
                 ]
    submit_tx    [type="ethtx" to="0x1Cc100f9c198d9CD3410263D4Df7FA7C5C30E34F" data="$(encode_tx)"]

    decode_log -> decode_cbor -> fetch -> parse -> encode_data -> encode_tx -> submit_tx
"""

我认为问题出在 abi=(uint256[] winners) 中的 encode_data 任务中。这是 uint256 数组的正确 abi 吗？

parse任务的输出是[6,14,25]，encode_data任务的输出是：0x000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000120000000000000000000000000000000000000000000000000000000000000006000000000000000000000000000000000000000000000000000000000000000e0000000000000000000000000000000000000000000000000000000000000019

我也认为编码任务结果不正确。

Answer 1

我通过更改 encode_tx 任务中 data 的 bytes32 参数类型解决了这个问题。
