A challenge that was never discovered during the 2021 Constellations mission... now ungated :)

Attachment: app.py

---

looking at app.py it will remove first character from name parameter name = name[1:] and put it in regex

results = re.findall(r"[A-Z][a-z]*?" + name + r"[a-z]*?\n", users, setting) in regex .* means everything and we can escape other conditions with use of or operator "|".

payload: A|.*|
