Just incase if anyone still facing this issue and couldn’t resolve, try to check this once.
I was able to fix this by going to the Orchestrator Collection, then ‘right click’ and click on [Edit collection], you will find a ‘Pre-request Script’ tab. You need to delete that script, apparently, there is an error somewhere in that script, or you may need to configure that before trying to run API calls.
In any case, I just needed to run simple API calls so decided to delete the script, and everything starts! to work.
