Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).
This bug belongs to the type errors pattern
Totals that concatenate, sorts that put 10 before 9, comparisons that refuse to run.
What went wrong: brackets alone do not make a tuple, the comma does. allowed is the text "admin", and "adm" is a piece of it.
The fix: allowed = ["admin"]
Remember: a one-item tuple needs a comma: ("admin",).
The pattern behind it: type errors.
