As a Roblox developer, it is currently impossible to get an error if an asset does not exist in the Asset Manager.
Example: I’m creating ImageLabels dynamically, through its name:
ImageLabel.Image = 'rbxgameasset://Images/' .. ImageName
But if the image does not exist within the Asset Manager, nothing will be shown.
If Roblox is able to address this issue, it would improve my development experience because when the asset referred by name doesn’t exist, I can handle the error, like to replace the image with another generic image.
