Display Spaces View Report erroring after upgrade

The script looks great in the editor, but now I'm seeing this error when I attempt to run it.  I know the server has rejected the request, but I'm not sure what to even tell our IT people. Can you help me with this at all?

Thank you, so much for what you provided above!

I'm running ScriptRunner 10.16.0.

Thank you so much for above.  The script looks great in the console, but when I run it, I'm now getting this error--I'm not sure what to even tell my IT guy--can you help?:

Very strange. 
I took code from vendor page, where they gave exactly this code, as example of new logic
https://docs.adaptavist.com/sr4c/9.x/release-notes/breaking-changes#api-changes
I slightly modified it, added some error catching, maybe that influenced.

Try this code, it's vendor code without my changes:

I'm still getting Status code: 401. Response body: oauth_problem=signature_invalid&oauth_signature....

I do really appreciate your help.  Here's what I need exactly:  The number of Views for each Global space on my Data Center Confluence 10.2.14 for the last 31 days.  I don't need any more customizations than that. 

I tried to google it, and it looks like, problem is not in script. Something wrong with instance configuration, maybe Confluence is behind reverse-proxy?
Your IT guy can check that the connector in Confluence's server.xml has scheme="https", secure="true", proxyName="confluence.bigxxxari-gc.com" and proxyPort="443", and that the proxy forwards the Host header unchanged.

Yes, me too. I've relayed what you wrote above.  I will post here and accept your answer as soon as I can.

The problem is our internal configuration.  Your first posted script (and the other) was clean and I'm sure it will work once we get our issue resolved. Thank you!!

Great! 
Good luck!
