Hope we're not in the same situation as Monomer, since in about 6 months, 9.4.x will be obsolete. :(

This should be fixed in version 0.6.2.2, can you try that version?

fimad commented 10 months ago

Verified in CI now that stackage support GHC 9.6.

Closing for now. If you are able to reproduce issues on 0.6.2.2 please re-open this issue.
