Intermediate Algorithm Scripting: Spinal Tap Case (Help)

**Doesn’t Allow me to Pass even though it prints the results as asked in the exercise **

spinalCase("TheAndyGriffith_Show") should return "the-andy-griffith-show"
It returns the exactly same in the log but someone says it doesn’t work

function spinalCase(str) {
  //changes the first character of str to UpperCase
  str = str.replace(str[0],str[0].toUpperCase());

  //Regular Expression with 4 different Capture Groups
  //Capture Group #1:(^[A-Z][a-z]+)
  //Capture Group #2:([A-Z][a-z]+| [A-Z][a-z]+| [a-z]+)
  //Capture Group #3:([A-Z][a-z]+| [A-Z][a-z]+|-[a-z]+)
  //Capture Group #4:([A-Z][a-z]+| [A-Z][a-z]+|_[A-Z][a-z]+|-[a-z]+)')
  const regex1 = new RegExp('(^[A-Z][a-z]+)([A-Z][a-z]+| [A-Z][a-z]+| [a-z]+)([A-Z][a-z]+| [A-Z][a-z]+|-[a-z]+)([A-Z][a-z]+| [A-Z][a-z]+|_[A-Z][a-z]+|-[a-z]+)');

  //Creates an array of individual words based on grouping from Regex1
  str = regex1.exec(str);

  //Removes 'spaces','dashes', and 'underscores' from word in each index
  str[2] = str[2].trim();
  str[3] = str[3].trim().replace('-', '');
  str[4] = str[4].trim().replace('-', '').replace('_', '');

  //str = str[1]+str[2]+str[3]+str[4] with '-'
  str = `${str[1]}-${str[2]}-${str[3]}-${str[4]}`

  return str.toLowerCase()

console.log(spinalCase('This Is Spinal Tap'));
console.log(spinalCase("Teletubbies say Eh-oh"))
console.log(spinalCase("AllThe-small Things"))

Looks like "TheAndyGriffith_Show" test case in reality is "The_Andy_Griffith_Show" and your code doesn’t handle it.
