Slot swap reset action deleted all application and connection strings

[mehmetcakmaz]

I use "az webapp deployment slot swap" command with -action reset option. This remove all application and connection strings settings including slot settings.

To Reproduce same situation

1. I create new web apps
2. Add new slot (name is = test)
3. Add sample application settings both slot (test and production)
4. Final status in test slot application settings
   
5. Run az webapp deployment slot swap --name xxx --resource-group yyy --slot test --action preview command
6. Run az webapp deployment slot swap --name xxx --resource-group yyy --slot test --action reset
7. Test slot application settings are deleted
   

Normally all settings should not be deleted. I tried the same issue Azure portal and "Switch-AzureRmWebAppSlot" everything worked as it should

Environment summary
Install Method is MSI / CLI version (2.0.43) / OS version Windows / Shell Type Windows

@panchagnula, any comments?

Yes, anything set as SlotSetting should not be deleted, this does seem like a bug on CLI end.

@mehmetcakmaz one clarification i need here before i start debugging this on the CLI end is that was the app settings, set as Slot Settings using CLI or portal?

I used the portal

@mehmetcakmaz, turns out the bug is in the CLI command where the default value for target-slot is not being set, run the --action preview command as follows

az webapp deployment slot swap --name xxx --resource-group yyy --slot test --action preview --target-slot production , followed by the reset command, We will have a fix deployed for this with our next release
