Deploying an app fails with following message.
Error: Scaling failed: disk_quota too much disk requested (requested 4096 MB - must e les than 2048 MB)
This happens when exceeding the max allowed disk size for an app.
Max allowed disk size for an app can be checked/configured in TAS Tile -> App Developer Controls -> Maximum disk quota per app .
Increasing that setting to the required size will resolve the issue
