You must install the main Mobile WMS extension before you extend it.
Install the latest version from AppSource marketplace
Download latest .App from University
When using Docker container it is recommended to specifically deploy to DevEndPoint. If no endpoint is specified, the ProdEndPoint will be used.
This may cause issues if you deploy older versions of you app as app files, but build and deploy newer version from VS Code.
VS Code will publish to DevEndPoint by default, and you will not be able to upgrade old Mobile WMS build if app and your code is not at same Tenant.
Verify the Mobile WMS Extension with version 5.0 or higher is installed.
