Here is the response

    "message": "Limit of: 5 extension schema definitions can be written.",
    "innerError": {

}

And here is the request body

{
"id": "myMetaData",
"description": "My description",
"targetTypes": [
    "Group"
],
"properties": [
    {
        "name": "shortName",
        "type": "String"
    },
    {
        "name": "supervisor",
        "type": "String"
    }
]

}

I have used delegated permision and used token generated by password since SchemaExtension needs delegated one and doesn't support application perm.

I got the answer , it was due to limit of the schemaExtensions that could be created other developer on the project already created 5 and since this was the limit set it showed this error
