Steps to Reproduce

Hi there. You should be able to fix this by updating your version of the TestRPC.

Please update to the latest version, and comment here if that does not fix your issue. Thanks!

[fabdarice]

I'm having the exact same issue.
Updated TestRPC & Geth and I'm using Geth regardless.

[adamdossa]

I'm having the same issue, debugging on the main net with geth 1.7.2

[makoto]

I upgraded to Ganache CLI v6.0.3 but getting the same error

[Ban44n]

Walking down the tutorial of http://truffleframework.com/tutorials/debugging-a-smart-contract and I experience the same error with geth v1.7.3-stable and Truffle v4.0.1

[szerintedmi]

same issue here
Truffle v4.0.1
EthereumJS TestRPC v6.0.3 (ganache-core: 2.0.2)

[stepanorda]

Same here with Truffle v4.0.1
Node v8.8.1
npm 5.4.2
Tried built in develop mode and Ganache

[kholbekj]

Also getting this - Truffle v4.0.1 | TestRPC v6.0.3

[bmmpxf]

I've encountered this too, exactly as described. It appears to be very inconsistent, with no discernible pattern. We'll need to investigate further.

[rohanp]

Same

[pferreir]

Having the same issue here. Maybe this needs to be reopened?

[jsdu]

Having this issue as well

[1for]

[tina1998612]

Same Issue here when using truffle debug...

[TimTinkers]

Also experiencing this under the same setup using the newest version of Ganache.

[Stradivario]

Previews week i was able to buyTokens from my contract using my api now i get the following error:

Then i try to debug transaction hash using:

truffle debug 0xa3ab41a32a00408f2f67b943f9aca529b940279b00defb0616ce59aab579000e

and i got the following error:

TypeError: Cannot read property 'structLogs' of undefined

Any recommendations ?
I think issue is related with https://github.com/trufflesuite/truffle/issues/748
i am facing both problems...

Regards,
Kristiyan Tachev

[robbiehanson]

same issue

Truffle v4.0.4
parity v1.8.6

[pvmraghunandan]

i am getting the same issue.

Truffle v4.0.5. Getting error as "TypeError: Cannot read property 'structLogs' of undefined". Is there any additional configuration required?

[bingtimren]

Hi, I got the same issue and may find out the problem: did you have a ; at the end of command? don't do that! See below two times running the same thing, the first failed because a ";" at the end and the second works.

I was still facing this issue with truffle 4.0.4 & 4.0.5 with the latest ganache-cli v6.1.0-beta.0
I had to manually edit truffle's cli js found here to fix it:
C:Users\\AppData\Roaming\npm\node_modules\truffle\build\cli.bundled.js

The error message gives out the line causing this error.
In my case it was in this method: Debugger.prototype.getTrace
I added a
console.info(result);
before the line accessing structLogs:
accept(result.result.structLogs)

Turned out that the getTrace call was rejected by the evm saying that there is a mismatch in the number of params being passed.
So changed this line:
params: [tx_hash],
to
params: [tx_hash, {}],

That fixed it for me. For others, the reason might not be the same, but you can follow the same steps to figure out what it is.

HTH.

[morozovsk]

same issue:
Truffle v4.0.6
ganache-1.1.0-beta.0-x86_64.AppImage

[pkoch]

I've successfully followed @saradotramli's instructions, things just started to work.

[EralpB]

same issue

[villesundell]

By following @saradotramli's debugging instructions, I noticed that for me the problem was:

{ jsonrpc: '2.0',
  error: { code: -32601, message: 'Method not found' },
  id: 1520947668993 }

This is because my Parity does not support (yet) "debug_traceTransaction" (https://github.com/paritytech/parity/issues/4858)

In my case, this is not Truffle's problem, but the error could be a bit more informative :D

[nullablebool]

Following @saradotramli method I was able to get further, I then ran into
TypeError: Cannot read property 'line' of undefined at Object.formatRangeLines (\node_modules\truffle\build\webpack:\~\truffle-debug-utils\index.js:211:1)

So as a quick fix, I just added the following two lines to this method:

formatRangeLines: function(source, range, contextBefore) {
    range.start = range.start || {line: 0, column: 0};
    range.end = range.end || {line: 0, column: 0};
