AM Custom Apps: Applications - A new application with an empty script may cause WA failure (ArgumentNullException: Value cannot be null. (Parameter 'text'))

This article is about product releases

ALVAO Asset Management Custom Apps 11.0 and higher

Symptoms

Saving a script with empty code returns hidden error. The window looks like it's still sending data.
Most of the WA pages don't work and return error "ArgumentNullException: Value cannot be null. (Parameter 'text')".

Cause

The cause is a bug in ALVAO products.

Solution

Fix planned for release ALVAO 26.4 (Q4 2026)

Workaround

Enter some code to the script before closing the window and save it or disable the application.
If you have already closed all the WA pages, disable the application with this SQL script: UPDATE Apps.App SET IsEnabled = 0 WHERE id = [appId]

Steps to reproduce this behavior

WA - Administration - Applications - New application
Edit scripts - New script - Empty template
Compile and save
Enable the application
