I also noted from here: <a href="https://app.roll20.net/forum/post/5412440/pf-pathfinder-companion-script-v1-dot-x-for-neceros-sheet/?pageforid=6984163#post-6984163" rel="nofollow">https://app.roll20.net/forum/post/5412440/pf-pathfinder-companion-script-v1-dot-x-for-neceros-sheet/?pageforid=6984163#post-6984163</a> <a href="mailto:doskious.steele+roll20@gmail.com" rel="nofollow">doskious.steele+roll20@gmail.com</a> had the same error message, asking: "Initially, I got the following error when attempting to over-heal a mook:....As regards the first error, the mook overhealing, is there a reason that there isn't a try/catch that, in the event of an un-linked barX (where barX is set to track HP in the Comapnion config), checks the token for a maximum value for barX and caps to that or reports an error maybe like, "BarX is set to track HP in your Companion config, but token {token reference} has neither a specified linked attribute nor a specified maximum value, so the Companion was unable to identify a valid maximim-cap for this token."?" I did create a mook token, but later deleted it and cannot bring up the config. It was working well prior to that. I've restarted the API Sandbox as well. Unsure what else I can try.
