WDC runs in Simulator but only blank tables when connected in Desktop

I have set up a WDC to connect to Bitly.  I am able to run and return data without errors on the Simulator, however when I connect via Desktop, it creates the tables but doesn't return data.  I have tried the suggestions already posted in the forums, like chunking the data into smaller pieces and using a cors proxy.  I have spoken with Tableau tech support and they think it might be due to the version of Tableau I am using (2020.1.2).  I have tried to run on both 2019.2 and 2019.3 and it doesn't work.  My question is if I use an earlier version of Tableau, do I also need to use a different version of the web data connector?  Has anyone run into this issue and resolved it?  I have been going around and around on this for several months, so any help would be greatly appreciated.

I spoke with an engineer at Tableau and this is what she responded:

Thanks again for talking with me about your case yesterday! I went through the logs again and it isn’t clear from the logs why the actual data isn’t being displayed in the UI. The logs show that we render the UI successfully but then we get a close event about a minute later.

TMainWindow received QEvent::Close

Shortly before the UI render we do see a connection-info-mismatch and this could be what is causing the data to now show up after we render the UI.

Any idea if this is causing no data to be returned and what I can do about it?
