Chainlink Node - encode_tx error incorrect length

I'm developing an external adapter and it's not working when I make a request to my local chainlink node. I have this error in the encode_tx step.

This is the error: ETHABIEncode: while converting argument 'data' from <nil> to bytes32: incorrect length: expected 32, got 32: bad input for task: bad input for task

This is the jobSpec:

type = "directrequest"
schemaVersion = 1
name = "eth-lottery-job-test4"
contractAddress = "0x1Cc100f9c198d9CD3410263D4Df7FA7C5C30E34F"
maxTaskDuration = "0s"
observationSource = """

                  data="$(jobRun.logData)"

I think the problem is in the encode_data task in abi=(uint256[] winners) . Is this the correct abi for an array of uint256?

The output of the parse task is [6,14,25] and the output of the encode_data task is: 0x000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000120000000000000000000000000000000000000000000000000000000000000006000000000000000000000000000000000000000000000000000000000000000e0000000000000000000000000000000000000000000000000000000000000019

I also believe that the encode task result is not correct.

Solution

  • I solved this by changing the bytes32 parameter type of data in the encode_tx task.
