Error on parsing content type header #2276
Description
I’m encountering a NoMethodError when some users send a Content-Type header like application/x-www-form-urlencoded,application/x-www-form-urlencoded. Could you help me identify the cause and resolve the issue?
Exception:
NoMethodError: undefined method 'start_with?' for nil (NoMethodError)
(str.start_with?('"') && str.end_with?('"')) ? str[1..-2] : str
