Are you using hardhat-chai-matchers? If so then yes it has known limitations documented here. Essentially it does not call tx.wait() but expects transaction receipt to already be available (which is semantically incorrect).

There might be a package that offers better matchers but I am not aware of one. As an alternative you can always write your own simple matcher that does wait for tx receipt before checking revert reason.

It worked before upgrading the test node, why would the package version be an issue?

Ah, sorry, I misunderstood what the problem is. Looks like there is indeed a bug in 0.6.4, I am looking into it.

Just released 0.6.5 with a fix. Please try it out
