Azure App Service deploy updating App Service Configuration linuxFxVersion settings to the wrong value

[salhidev]

Issue Description

The Azure App Service deploy task updating the App Service Configuration settings to a wrong value:
Trying to update App Service Configuration settings. Data: {"linuxFxVersion":"6.0 (DOTNETCORE|6.0)","appCommandLine":"dotnet MyService.dll"}

This results to setting the stack in the app service configurations from .NET to nothing selected. Which breaks the app service.
Looking at the change log I see this :

Operation system

Linux

Looking at the template, the linuxFxVersion value should be :
"linuxFxVersion": "DOTNETCORE|6.0"
And Not
"linuxFxVersion": "6.0 (DOTNETCORE|6.0)"

Hi @salhidev , was this task working fine before(2-3 weeks back) with the same configuration? if so can you let me know the task version used in success run (eg 4.229.0)

@v-mohithgc the problem happens sporadically, I don't see any pattern.
