8,377 Pointsyou haven't posted your code, but I'll try and recreate the error.
let props = {
players: []
}
let totalPlayers = props.players.length; //works
props = {
}
console.log("running1");
totalPlayers = props.players.length; //fails
console.log("running2");
produces output of:
VM192:9 running1
VM192:10 Uncaught TypeError: Cannot read property 'length' of undefined
at <anonymous>:10:30
So you should probably verify if there's an array at props.player.

18,814 PointsIt will be difficult to troubleshoot with only this short snippet. If you're able to post a workspace snapshot using the camera icon towards the top right, or post your code using markdown it will help community members help you!
It may also be helpful to link to or give the title of the course you're working from.
