Volume Measurement not working - Latest WebODM

Recently about a month back, I installed webODM and just now noticed that volume measurement is not working anymore. The wheel keeps spinning with so many rest requests/response on the UI. I even updated to the latest (as of 7/21/2020) and here is the information. It used to work couple of months back and kindly advise. It is very urgent and thanks a lot.

Rest request - https://wedodm/api/plugins/measure/task/b4b712b0-9c2e-4c9a-bc10-dcf37d4ba3f1/volume/check/d5993f65-dc83-4506-839b-f70fb84f8ac8
Response - {“ready”:false}

In the webODM console, I just get this
