You said your json is a variable, but you don't mention which type it's stored.

  1. Stored as string. In this way the whole json is a string, it's not supported to select property. So you need parse it to Json with Parse JSON action then you will be able to select property. About the Parse JSON Schema, just click the Use sample payload to generate schema and paste your json value, it will generate. And select your property just use the @{body('Parse_JSON')?['name']}, it will work.

  1. If it's stored as an Object, it will be easier to do it, just use expression variables('test1')['name'] to get it.

Use the Parse Json action and use your payload as a "Use sample payload to generate schema". After that, id will be listed as a Dynamic content from the Parse Json action.
