You need deploy Mobile WMS extension before you can extend it

Here are your options:

Saas/Cloud:

Install the latest Mobile WMS app from AppSource marketplace

Docker / On-Prem:

Download latest App from https://university.taskletfactory.com/
- Create 14.0 or 15.0 Docker Container
- Publish Mobile WMS App to DevEndPoint

Source Code

Download latest Per-Tenant App from https://university.taskletfactory.com/
- This will give you full view of the source code for reference / inspiration / copying.
- Do not deploy the PTE app unless you want to "own" all the source code (NOT recommended)

Important

It is recommended to specifically deploy to DevEndPoint when developing against Docker containers.

If no endpoint is specified, the ProdEndPoint will be used.

This may cause issues build and deploy the Mobile MWS Per-Tenant Source Code yourself - specifically, if you deploy older versions of you app as app files, but build and deploy newer version from VSCode..

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.

Verification

Verify the Mobile WMS Extension with version 5.0+ is installed.
