How to pass UserData when executing crawler

When I do await crawler.run(['https://crawlee.dev'], { userData: { depth: 0 } }); I got this error: Uncaught ArgumentError ArgumentError: Did not expect property userData to exist, got [object Object] in object options How can I set userData in option? `

await crawler.run([{url: 'https://crawlee.dev', userData: { depth: 0 } }]);

userData is part of request, not part of crawler

You passed the userData as the second parameter of the run() method instead of within the request. Hence the ArgumentError. Try this instead:

await crawler.run([{
    url: 'https://crawlee.dev',
    userData: {
        depth: 0,
    },
}]);

await crawler.run([{
    url: 'https://crawlee.dev',
    userData: {
        depth: 0,
    },
}]);

Also, something that was not obvious to me was how to get the user data on the route. you can do it like so

const routeHandler = async ({ request, crawler, page, log }) => {
    // get user data
    let { depth } = request.userData  
}

const routeHandler = async ({ request, crawler, page, log }) => {
    // get user data
    let { depth } = request.userData  
}
