"$schema" is missing after deployment of standard logic app workflow

[Revathi2024]

After deployment of standard logicapp as zip package using Github action "$schema" is missing in all workflow of standard logic app
as below
"definition": {
"": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
"actions": {....
}
}

please help me on this to resolve it. "$schema" should appear post deployment in all workflow of the standard logic app.

Thanks in advance
