@marlowe-shaeffer Due to the bug that prevents dropdowns from working properly in my app in preview mode, I have been testing the affected feature live. By modifying my app to be able to test the feature in preview I discovered the reason http-functions stopped working. I had removed some old files that were no longer used and one of them was being imported in http-functions. Because I had only removed files that were no longer being used, I believed no code changes had been made thus the problem was not induced by me. I somehow missed the import when I did a global search for it.
I fixed the problem. Thanks for your help. The prompt to test in preview got me over the hump.
As a side note, had preview worked properly this issue would have been nipped in the bud. I notice that it still has not been fixed. I reported it and supplied a video showing the issues on the 12th of this month. I hope they are still pursuing the problem as this issue has resulted in a lot of waisted time.
