Error when deploying azure static web app through github

Hello, my blazor webassembly is using .net8.0.400. I have created static web app and added my github repo.
And I have an error when I do the "Build and Deploy job through github ci/cd"

The command could not be loaded, possibly because:
* You intended to execute a .NET application:
The application '--version' does not exist.
* You intended to execute a .NET SDK command:
A compatible .NET SDK was not found.

Requested SDK version: 8.0.400
global.json file: /github/workspace/global.json

Installed SDKs:

Install the [8.0.400] .NET SDK or update [/github/workspace/global.json] to match an installed SDK.

Learn about SDK resolution:

Am I not able to use .net 8.0?

Beginne mit dem GitHub build-and-deploy workflow und dem in der Fehlermeldung angegebenen global.json-Pfad; vergleiche das angeforderte .NET SDK 8.0.400 mit dem, was der Job bereitstellt. Erledigt ist die Aufgabe, wenn der Workflow die Blazor WebAssembly-App ohne den SDK-resolution error erstellen und bereitstellen kann.
