I have never seen this error before. It is a roc runtime error:
Roc crashed with:
voided tag constructor is unreachable
Here is the call stack that led to the crash:
InternalTask.ok
Task.ok
Task.(anonymous function)
.(anonymous function)
Any ideas?
Hitting it in the sqlite.roc
example here: https://github.com/roc-lang/basic-cli/compare/main...ffi
Found a workaround. Still not exactly sure what is wrong, but I think I built code with uncontrained types passed to effects and that is what broke things.
seems like a miscompilation
