Hello, I’m a beginner in Twitch extension development, I have just downloaded the Hello World extension and uploaded the .zip file by creating a new extension in my twitch developer account. Now the panel is coming on my channel but getting this error **“Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”).”** in the console and js functionalities are not working. I have tried a lot but unable to find out the reason. Can anyone please help me out of this problem? ![panel_error](https://d2spem0quai2ol.cloudfront.net/original/2X/8/8be2f79889388e9ba84f8e17f0212ce573bb09dd.png) ---

This looks like the older hello world. Extensions in hosted test cannot use jQuery (and other libraries from a CDN). Try the hello world obtained via the Native rig which is more up to date. > [@A New Direction for the Twitch Developer Rig](https://staging-discuss.dev.twitch.com/t/a-new-direction-for-the-twitch-developer-rig/19565): > > Today (January 17, 2019), we’re announcing the steps we’re taking to improve the way we build and deliver the Developer Rig. Our mission is to help developers build the best Extensions possible, and we believe we can better serve our customers by taking development fully in-house and moving the Developer Rig to a closed source model. The immediate outcome of this strategic decision is the [native Developer Rig](https://staging-discuss.dev.twitch.com/t/announcing-the-native-developer-rig-beta/19126), which is currently in beta.

Thank you. My problem is solved. It’s now working. But I have a query here, can I open a new window having a 3rd party web url, by clicking a button within the Twitch extension using js? ---

_shrugs_ I can see that extension is fully functional, and pops open a popup window. > [@Somnath\_Ghosh](#): > > But I have got a similar here [Twitch](https://www.twitch.tv/fuzzface49) Seems weird you already have a working extension but now having problems with hello world… The errors in your screenshot have nothing to do with Twitch Extensions they indicate issues with the cart JS Library ---

No that extension is just a reference and I’m just trying to make an extension like that. Ok if it has nothing to do with Twitch extensions, I will check the cart js. Thank you @BarryCarlyon. ---

A twitch extension cannot natively access a database, your extension would have to make a ajax call to your EBS and the EBS performs the DB looking up returning that data. ---
