Truffle: Debugger seems to be broken on 4.1.6

[glitch003]

• [X] I've asked for help in the Truffle Gitter before filing this issue.

Issue

Debugger is outputting an error when trying to debug a txn on latest truffle (4.1.6)

Steps to Reproduce

Installed latest truffle, unboxed metacoin, deployed to ropsten, did a sendCoin successfully, tried to debug that sendCoin txn and getting the error below: TypeError: Cannot read property 'contractName' of undefined

Expected Behavior

Truffle should debug the txn and let me step through it

Actual Results

h4ckb00k-new-2:Metacoin chris$ truffle console --network ropsten
truffle(ropsten)> debug 0xcc297cc9e06bd3d2ad041442c3e396397c38bc842de9f82e064d6d955de88ce4

Metacoin is deployed at: https://ropsten.etherscan.io/address/0x3f0e61774c4a4f0e0b50649cb289c3cd2a599c7e

This is the txn I was trying to debug: https://ropsten.etherscan.io/tx/0xcc297cc9e06bd3d2ad041442c3e396397c38bc842de9f82e064d6d955de88ce4

[gnidan]

@glitch003 just in case this applies, did you deploy to Ropsten before upgrading Truffle? If you look at the JSON artifact files for deployedBytecode (or deployedBinary, I forget which), does it match what's deployed on Ropsten?

[glitch003]

@gnidan I am fairly certain that deployed after updating truffle, but, the bytecode indeed doesn't match. In fact, the deployedBytecode in the JSON artifact has a weird ascii string in it (ConvertLib).

This is the deployedBytecode from the JSON artifact files, and there's also a link to the actual deployed bytecode on etherscan at the bottom:

[gnidan]

Hm @glitch003 these actually look the same. That __ConvertLib____________ bit gets replaced at runtime, so you should be able to ignore that.

Not sure what's going on, but we should have another Truffle release out in the next few days that might fix the issue.

[glitch003]

@gnidan Okey doke, will wait and try to reproduce on next release. Thanks!

[gnidan]

@glitch003 try now with Truffle v4.1.7

[glitch003]

@gnidan same thing, unfortunately :(

[artemistomaras]

I have the same problem using [email protected] and Ganache for development.

[gnidan]

I believe this has been fixed on develop and will go out with 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 [email protected]

Here's my whole console session including the contract deploy and making the txn that I'm trying to debug: https://gist.github.com/glitch003/0e90a4ead0f0dac7797b5a6169b7b8e5

@glitch003 can you try adding --compile-all to your migrate command and let me know if that helps:

darq-truffle migrate --network ropsten --reset --compile-all

I suspect there might be a problem with your artifacts being out of date? Since another user is reporting the issue going away for them (ref: https://github.com/trufflesuite/truffle-debugger/issues/64). Let me know if that doesn't solve it!

@gnidan it worked! Hurray! Thanks so much for following up!
