scenarios when deploying a Solidity contract using Truffle - 'how to read property 'abi' of undefined'

truffle solidity smart-contracts Solidity

I tried several approaches but none seem to work. I'm working on a project and hit a roadblock. I'm trying to deploy a simple Solidity contract using Truffle (version 5.4.0), but I keep running into this behavior: `want to read property 'abi' of undefined`. This happens when I run `truffle migrate --network development`. I have checked my contract's name and the setup in the `migrations` folder, but everything seems correct. Here’s the code for my simple contract, `MyContract.sol`: ```solidity // SPDX-License-Identifier: MIT pragma solidity ^0.8.0; contract MyContract { string public message; constructor(string memory initialMessage) { message = initialMessage; } function updateMessage(string memory newMessage) public { message = newMessage; } } ``` In my `migrations/2_deploy_contracts.js` file, I have: ```javascript const MyContract = artifacts.require("MyContract"); module.exports = function (deployer) { deployer.deploy(MyContract, "Hello, Blockchain!"); }; ``` I made sure to run `truffle compile` successfully before trying to migrate. Additionally, I verified my `truffle-config.js` to ensure the development network is configured correctly: ```javascript module.exports = { networks: { development: { host: "127.0.0.1", port: 7545, network_id: "*" } }, compilers: { solc: { version: "^0.8.0" } } }; ``` I've also tried deleting the `build` folder and recompiling. However, the behavior continues. The Truffle console also does not show any issues when I compile. Could there be an scenario with the way I'm importing or declaring my contract? Any insights on how to resolve this would be appreciated! For context: I'm using Solidity on macOS. Thanks in advance! I'm working with Solidity in a Docker container on Debian. Am I missing something obvious?
