When specified, "proxy" in package.json must be a string. Instead, the type of "proxy" was "object". Either remove "proxy" from package.json, or make it a string. code example

Example 1: The "chunk" argument must be one of type string or Buffer. Received type object nodejs

//change res.end() to res.send()

Example 2: Write a function isRed() that accepts a string parameter and looks for the presence of the word ‘red’ in the string. If it is found, return boolean True otherwise False. Finally output the result of calling the function with the value in text.

def isRed(redexistance):
  output = redexistance.find('red')
  if output < 0:
    return 'False'
  else:
    return 'True'
print(isRed(text))

Example 3: Expected a state variable declaration. If you intended this as a fallback function or a function to handle plain ether transactions, use the "fallback" keyword or the "receive" keyword instead.
