@Ian_Foster it looks like you’re using a legacy API key with robocrys. I just tried an API key for our new / next-gen API (the one @Aaron_Kaplan was eluding to) and the latest version of robocrys. It still results in the following error but that might be a different issue - see
- Error for ElementProperty Source:Magpie - #6 by Chaozhuang22 and
- Two Issues with importing `ElementProperty` - #2 by bobleesj
