`to.be.revertedWithCustomError()` doesn't work on Sapphire

[matevz]

SUMMARY

Perhaps related to #686, this works:

await expect(myContract.myFunction())
    .to.be.reverted;

while

await expect(myContract.myFunction())
    .to.be.revertedWithCustomError(myContract, "SomeError");

yields

AssertionError: Expected transaction to be reverted with custom error 'SomeError', but it didn't revert

although the transaction was reverted with the correct error (I checked the localnet explorer), so it just wasn't caught by the wrapper.

ACTUAL RESULTS

Exception is thrown that the tx wasn't reverted.

EXPECTED RESULTS

Tests should pass normally.

FYI revertedWithCustomError() seems to work in the quiz tests: https://github.com/oasisprotocol/demo-quiz/blob/main/backend/test/Quiz.ts

yes because these are eth_call, the problem is on state changing transactions
