error when searching tweet.text with includes()

[Edmund1645]

I'm trying to search tweets that come into the stream if they contain a specific username but I get an error: tweet.text.toLowerCase(...).inludes is not a function at StreamingAPIConnection.stream.on.tweet

i use it like this: if (tweet.text.toLowercase().includes('@username'){ // like tweets }

Can you show us how you setup your stream?
