I'm trying to create a contract that communicates with JIRA API through Chainlink Oracle on the Goerli Network. The interaction should create a JIRA project, then write some of the returned JSON's data into the blockchain.

Heres my contracts:

JIRA Manager (Called Fractal Forge Manager):

    pragma solidity ^0.8.0;

import "@chainlink/contracts/src/v0.8/ChainlinkClient.sol";
import "@chainlink/contracts/src/v0.8/ConfirmedOwner.sol";
import "../game/GameData.sol";

contract FractalForgeManager is ChainlinkClient, ConfirmedOwner {

    address public constant EMPTY_ADDRESS = 0x0000000000000000000000000000000000000000;

    //Chainlink config
    using Chainlink for Chainlink.Request;

    address private oracle;
    bytes32 private jobId;
    uint256 private fee;

    // Fractal Forge Data:
    GameData[] public projectList;

     * Goerli Testnet details:
     * Link Token: 0x326C977E6efc84E512bB9C30f76E30c160eD06FB
     * Oracle: 0xCC79157eb46F5624204f47AB42b3906cAA40eaB7 (Chainlink DevRel)
     * jobId: 53f9755920cd451a8fe46f5087468395
    constructor() ConfirmedOwner(msg.sender) {
        jobId = "53f9755920cd451a8fe46f5087468395";
        fee = (1 * LINK_DIVISIBILITY) / 10; // 0,1 * 10**18 (Varies by network and job)

     * Create a Chainlink request to retrieve API response, find the target data
    function createGameProject(string memory projectName, string memory projectKey) public returns (bytes32 requestId)
        Chainlink.Request memory request = buildChainlinkRequest(jobId, address(this), this.fulfillMultipleParameters.selector);

        // Set the URL to perform the POST request on
        request.add("post", "https://latinosystems.atlassian.net/rest/api/latest/project");
        request.add("body", string.concat("{",
        "\"key\": \"",projectKey,"\",",
        "\"name\": \"",projectName,"\",",
        "\"projectTypeKey\": \"software\",",
        "\"leadAccountId\": \"557058:aed543b7-1ccc-4eea-9eb5-07fb1a44da29\",",
        "\"projectTemplateKey\": \"com.pyxis.greenhopper.jira:gh-simplified-agility-scrum\"",

        request.add("path", "key");

        // Sends the request
        return sendChainlinkRequest(request, fee);

    function fulfillMultipleParameters(bytes32 requestId, string memory key) public
        GameData newGameProject = new GameData(key);

    function getProjectList() view public returns(GameData[] memory)
        return projectList;

    function getGameDataByKeyName(string memory key) view public returns(GameData)
        return projectList[0];
        for(uint256 i = 0; i < projectList.length; i++)
            if(keccak256(bytes(projectList[i].gameJiraKey())) == keccak256(bytes(key)))
                return projectList[0];
        revert('Not found');

ProjectData (called game data)

//SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.0;

contract GameData
    struct GameBounty
        string jiraTaskID;
        uint256 bountyPrice;
        uint256 jiraScore;

    string public gameJiraKey;
    GameBounty[] public bounties;

    constructor(string memory createdGameJiraKey) public
        gameJiraKey = createdGameJiraKey;

    function calculateTotalPoints() public view returns(uint256)
        uint256 totalScore = 0;
        for(uint256 i = 0; i < bounties.length; i++)

        return totalScore;

Through brownie, I tried to call FractalForgeManager's createGameProject right after deploying the contract, adnd themethod was called but it just didn't register anything on the blockchain. To further test, I simply called the already existing contract like this:

self.fractalForgeManager = FractalForgeManager.at(address)

Then tried calling the createProject method

self.fractalForgeManager.createGameProject(projectName, projectKey)

But when I try to call createGameProject, I get the following error (my contracts are funded and I have eth on my test wallet):

Running 'scripts\deploy\Deploy.py::main'...

    raise AttributeError(
AttributeError: Final argument must be a dict of transaction parameters that includes a `from` field specifying the sen
der of the transaction

Any idea what the issue may be here?

Solves, just added a map with "from"and "account" at the endof my method's parameters.

self.fractalForgeManager.createGameProject(projectName, projectKey, {"from": self.account})
