Unable to import any extension in ThingWorx 8.4
I just installed ThingWorx platform 8.4 with MSSQL as a persistant provider. The installation has been done with success. No error in the Tomcat as everything as stated properly. However, whenever I tried to import an Extension, I am getting a generic error like: Errors occurred during the validation or the import. There is nothing showed in the application log. Any idea how to solve or troubleshoot this issue?
