Regex is not matching in Scala

I want to split up a camelCase string with spaces.

"ClassicalMusicArtist" -> "Classical Music Artist"

I should be able to do this by replacing "/([a-z](?=[A-Z]))/g" with "$1 " (regex101).

But my regex is not getting any matches:

val regex = "/([a-z](?=[A-Z]))/g".r
val s = "ClassicalMusicArtist"

regex.replaceAllIn(s, "$1 ") // -> Returns "ClassicalMusicArtist"
regex.findFirstIn(s) // -> Returns None

What am I doing wrong? I used the regex in another language with success and can't figure out why I am not getting any matches.

Ok I figured it out.

In scala the regex has to be val regex = "([a-z](?=[A-Z]))".r without the leading / and the modifier.
