There's a typo in the example: 'taticweb00' should be 'staticweb00' to match the expected static web app naming convention.

Suggested change

	Get-AzStaticWebAppBuildAppSetting -ResourceGroupName resourceGroup -Name taticweb00 -EnvironmentName 'default' | New-AzStaticWebAppBuildAppSetting -AppSetting @{'buildsetting1' = 'someval'; 'buildsetting2' = 'someval2' }
	Get-AzStaticWebAppBuildAppSetting -ResourceGroupName resourceGroup -Name staticweb00 -EnvironmentName 'default' | New-AzStaticWebAppBuildAppSetting -AppSetting @{'buildsetting1' = 'someval'; 'buildsetting2' = 'someval2' }
