Not able to debug a contract created by another contract that subsequently causes the transaction to revert

Issue

I’m trying to debug a transaction - I’ve got all the contracts linked to source code except one…

Addresses affected:
 0xe78A0F7E598Cc8b0Bb87894B0F60dD2a88d6a8Ab - ProcessRegistry
 0x7C728214be9A0049e6a86f2137ec61030D0AA964 - BindingAccessControl

 0x5f8e26fAcC23FA4cbd87b8d9Dbbd33D5047abDE1 - Order_To_Cash_worklist
 0x8C6AAd0C92a48112aAa0e6e8F98A160120f17059(UNKNOWN)

It turns out the one I can’t link has a null binary - but it is in this one where the error is occurring.

All the others have been deployed by web3 - the one with the null binary (0x) has been created by another contract:

Goods_Shipement_Contract newContract = new Goods_Shipement_Contract(parent, worklist, processRegistry);

is there any way such contracts can be linked to their source code so they can be debugged?

For reference the null binary gets returned here: packages/truffle-debugger/lib/session/sagas/index.js

let binaries = yield* web3.obtainBinaries(addresses, blockNumber);

Steps to Reproduce

I can provide my source files if you’d like… + ganache-cli data

Environment

• Operating System: ubuntu
• Ethereum client: ganache-cli
• Truffle version Truffle v5.0.17 (core: 5.0.16)
• node version Node v11.14.0
• npm version 6.7.0

OK, I’ve just put up PR #2052 which should fix this. Note that you’ll still get that (UNKNOWN) display on startup, but you can ignore that; once this is merged the call itself should work fine.

OK, great! In that case I’m pretty sure I know what I need to do to fix this.
