Truffle debug

Do you have any guide to debug smart contract transactions if proxy-contract used?
Or it is not a proxy issue?

Hi,

There isn’t a guide to debug upgradeable smart contract transactions that I am aware of.

I assume that truffle debug doesn’t support proxy contracts. I tried and got the same error as you.

You could track down any potential issues just using your logic contract. Otherwise feel free to share your contract.

Oh, I got it.
Just need to execute one step next (n), and debugger jumps to logic contract source code.
Thanks!

Nice solution.
I have written this up as a guide: Debugging OpenZeppelin SDK contracts with truffle debug
