I don't know if this is a known issue or not, I couldn't find a topic that was specific to this script.  I own the Tomb of Annihilation module and it's loaded in my game.  I have the companion script and !autonpctoken is turned on.  When I click the health formula for an NPC from the ToA module it doesn't generate a token and the API Output Console has this error.  "ERROR: You cannot set the imgsrc or avatar of an object unless you use an image that is in your Roll20 Library. See the API documentation for more info." Is this the way it was intended to work?  I purchased these modules, and I don't have access to them? Edit: Sorry I found it finally, apparently it's for security reasons, which I'm fine with, but maybe update the Help Wiki with that info if that's the intended way it's to be used.
