The same code is running without in the production tenant with the same backend.
replacing https with xxx to by-pass check for link that is not allowed

Hi Eddie, 10.9 is quite old at this point, do you need to use that rather than the latest?

It looks as if our JSON codec thinks the JSON returned from /inventory/managedObjects is invalid (specifically it’s complaining that it looks like {…}somethingelse ). Assuming that your inventory is not actually returning corrupt data, it smells like a bug. We have completely rewritten this code in 10.15. Are you able to provide the actual response you get (possibly from postman) for that query?


Upgrading to 1015 seemed to solved the problem.
Thanks Matt!
