This test is currently ignored: https://github.com/keep-starknet-strange/madara/blob/38ef50e00a7c53ef55b5b2eb9a9f59426738de03/starknet-rpc-test/get_class_at.rs#L47C13-L47C20
until #1469 is solved.

Which is the purpose of your PR #1523.

This issue seems to say that the test is failing at a commit that does not contain your PR changes. Does it still fail on your #1523 branch?

@tdelabro Thank you for your commit. This issue arose from a recent update to the codebase. My PR #1523 addresses the missing "main_scope" field reported in issue #1469. The solution was tested with commit 5e68494.

[tdelabro]

@fishseabowl can you list the next steps please? What to merge now? What to fix later?

@tdelabro The PR #1523 is ready to be merged. After that, we'll look into why ContractClass::Legacy serde_json format isn't decoding correctly in this issue #1585 and fix it. Thanks

#1523 has been merged
