APE-1753 Ape version 0.8 got `Reason: Missing kwargs: ['nonce']` when making transactions in tests

Just to verify, renaming Nonce.vy to something else doesn't change the behavior does it?

Nope. The original example is coming from here: https://github.com/PacktPublishing/Hands-On-Blockchain-for-Python-Developers--2nd-Edition/tree/main/chapter_6/voting_app

That's not the only one. Another example is: https://github.com/PacktPublishing/Hands-On-Blockchain-for-Python-Developers--2nd-Edition/tree/main/chapter_16/dex

Many code for my upcoming book are broken with Ape 0.8.

What network / provider are you using?

What network / provider are you using?

I was running the test when I got the error.

(.venv8) $ ape test

What is the provider being used when we're running the test? Don't know. EthereumTester (eth-tester) perhaps?

eth-tester is the default but most projects these days use ape-foundry or ape-hardhat which offers better tracing support needed for coverage and stuff.

Nonetheless, thank you! This is the info I need to help repro and fix the problem(s). ◡̈

[antazoey]

I have a fix incoming for this!

[arjunaskykok]

Thanks!
