6 years ago Thanks for the great reproduction steps!
Right now we don't support debugging tests for technical reasons. (See #44)
I'll look into this on Monday and see about improving the error message at least.

6 years ago Ah, I wasn't aware of that. I remember that debugging on test was working at some point in the past. This explains why I can debug transactions on migration contract.
Thanks.

6 years ago Ummm, am I misunderstanding something?
I ran the migration and send a transaction from truffle console directly and try to debug an transaction but still getting the same error. Does debug not work against Ganache at all?

6 years ago @makoto this fix should be good to go in the next release.
In the meantime, I've just published a nightly release with this change. If you could, please install that and let me know if the problem goes away for you:
npm install -g darq-truffle@4.1.7-latest.2
darq-truffle debug 0x...Thanks!

6 years ago Looks working! Great job 👍
The fact that I can see variables are life saver. Can't wait to be able to do this against tests, too.

6 years ago Hi, @gnidan .
To work around the issue of not being able to debug the test, I am currently trying to deploy test contract and try to invoke manually but failing because migration script is not aware of where truffle/Assert.sol exists (I
also moved from test directory as migration seem to only compile things on contract dir, not test contract under test/ dir. Wondering if it's possible to point to the right path.

Your contracts may have been compiled with two different solc versions. Let me know if that doesn't fix it!

6 years ago @gnidan I tried this multiple times. What's interesting is that debugging for some method calls work fine, while don't work for that specific method. I'll investigate more.

6 years ago Hi, I'm getting this TypeError: Cannot read property 'context' of null error too while I'm trying to instantiate a new Debugger object.
Here there is a snippet of my code ( which is similar to this ).
if (this.debuggerConfig == null){
let options = ['.', '.', 'development'];
var config = new Config(...options);
var [contracts, files] = await this.compileContract(config);
// from: https://github.com/ethereum/web3.js/issues/1119
Web3.providers.HttpProvider.prototype.sendAsync = Web3.providers.HttpProvider.prototype.send;
this.debuggerConfig = {
provider: new Web3.providers.HttpProvider("http://localhost:8545"),
files: files,
contracts: Object.keys(contracts).map(function(name) {
var contract = contracts[name];
return {
contractName: contract.contractName || contract.contract_name,
source: contract.source,
sourcePath: contract.sourcePath,
ast: contract.ast,
binary: contract.binary || contract.bytecode,
sourceMap: contract.sourceMap,
deployedBinary: contract.deployedBinary || contract.deployedBytecode,
deployedSourceMap: contract.deployedSourceMap
};
})
};
}
// Create a new debugger instance given the txHash and initialize the session
const bugger = await Debugger.forTx(txHash, this.debuggerConfig);
const session = await bugger.connect();I have no problem if I run the debbuger from command line (truffle debug <txHash>).

6 years ago @etnann are you using Web3 1.0?
Could you show me what files looks like?
etnann
commented
6 years ago @gnidan Yes, the latest available on npm (1.0.0-beta.34).
I attached a debugger, the variable files is a an array of strings. Contains two strings
contracts/BecToken.sol
contracts/Migrations.solHere you can see some of the variables before the call Debugger.forTx
The variable contracts is generated calling the compile.all method in truffle-compile.
I've updated the comment https://github.com/trufflesuite/truffle-debugger/issues/64#issuecomment-391667530 with the few lines on top of the existing code (compileContract is a wrapping of the function compile.all inside a Promise).

commented
6 years ago I've re-written my code so that contracts list is generated from the artifacts in the build directory instead of re-compiling again from the solidity source. Then, I've also omitted the field files. Now it is working and I'm able to instantiate from the Debugger class. :confused:
Hi, I just installed the latest ganache/truffle and try to debug transactions against metacoin but failing with the error.
