User-reported unhelpful error message

**Program:** https://code.world/#PY_mFE2apufaKkR4Kr0GcGg

**Comment:**

it keeps saying I am missing a parantheses over and over and over again every time I add one it asks for another

**Message:**

program.hs:20:10: error:
parse error
• Are you missing a parenthesis?

The issue names only a CodeWorld program URL and a Haskell parse error, so start by reproducing that program and locating the parser diagnostic path. Confirm what causes the repeated parenthesis suggestion; done should be a clear, accurate diagnostic for this input, with regression coverage if the project has a suitable test location.
