There are two possible causes for this issue:

  • ​​​Scenario 1: Uploading an application that is created using another platform  
    • When an application is created using applications other than Web AppBuilder for ArcGIS and uploaded to Web AppBuilder for ArcGIS, the folder format may not follow the required format.
  • Scenario 2: Uploading an application after editing
    • When an application created using Web AppBuilder for ArcGIS is downloaded and edited, the folder structure may not use the required format. This may happen when the user performed changes to the application, such as adding custom widgets (which involves JavaScript or CSS files).


Solution or Workaround

Use one of the following workarounds according to the scenario involved.

Scenario 1: Uploading an application that is created using another platform  

  1. Create a new application by clicking Create New, and select the desired type of application.
