Stuck at oAuth Step in Shopify PHP App Development

[KabirDev]

I'm attempting to build my first Shopify app using PHP and I've hit a roadblock at the oAuth step. Instead of redirecting to the oAuth admin page as expected, it takes me to the Shopify home page. I've attached both a screenshot of my code and a video to demonstrate the issue. Does anyone have any insights on how to fix this? Thank you!

I solved it. The problem was in the 11 no. line. I used `grant_options` but it should be `grant_options[]`. Thanks.
