Good day all, I am learning Solidity, and I came up with this issue while deploying my contract yesterday.
So I can deploy it correctly, and the calls to the readonly function getVotes() seem to work ok.
When I deploy it on test net, and use tronBox (in a browser environment)
const tronWeb = window.tronWeb;
const contractAddress = 'TFBP2xBhYTb2hNrLep5UpFW1a2DZ5AP4yY';
let contract;
try {
contract = await tronWeb.contract().at(contractAddress);
} catch(e) {
console.error(`error loDING CONTRACT ${contractAddress}`);
throw e
}
//
//
try {
let votes = await contract.getVotes().call();
console.log(`Loading All votes from TRON `, votes);
} catch(e) {
console.error(`error getting votes`, votes);
throw e
}
try {
const txId = await contract.voteBooks([35, 36], [3, 4]).send()
console.log(`Check tx on the explorer: https://shasta.tronscan.org/#/transaction/${txId}`);
} catch(e) {
console.error(`error voting`, e);
throw e
}
The 3d try/catch block doesn’t throw any error, and the console log shows check tx on the explorer:
When I go check it out, the transaction failed, and I cannot find any debug information that could help me figure out what is going on, and why it failed. So I am turning to the TRON experts out there that eat solidity at breakfast, and can spot bugs effortlessly while doing cardio.
Here is the contract on Shasta: TRONSCAN | TRON BlockChain Explorer | 波场区块链浏览器
I cannot seem to explore why the transaction failed, and I am quite stuck.
Here is the contract source code:
