Just to confirm, are you using the perspective app(I don't think it works in perspective workstation yet)? Or a web browser? The below link discusses the limitations of the camera access. Otherwise, it might be an app permission on the device itself.

> No, the barcode action may ONLY be called by devices using the mobile application. If you try to call the Scan Barcode Action from a browser, you’ll notice a warning in the console, that your Action was ignored. We can’t call that action from a browser, because not every workstation has a camera.
