Scenario: 2 developers with Web AppBuilder 1.2 installed on each local C:\ for developing WAB apps and deploying to Organization ArcGIS Online.
1. Developer #1 has WAB app up and running in production.
2. Emergency change requested while Dev #1 is out of office.
3. Developer #2 is asked to make the requested updates.
So, Developer #2 locates the .zip containing the deployed WAB app and copies to local C:\ where the WAB Builder 1.2 is installed. A session is started ("Startup.bat") and an attempt to Import the .zip project fails with "Error parsing server result".
Any ideas on what's wrong? What to look for? What to do?
