The package cache is where AL looks for the references to the objects in the dependent apps. This is also called ‘symbols’. If the symbols are not in the package cache, you need to download them, so run the ‘download symbols’ command from the command palette. Normally when you create a new AL workspace, you already have a container or a service tier set up as the target, which is defined in your launch.json file.
