Hi @Mickey248
Please make sure that the reverse directive is created in the schema as below for “source_with_sympton”.

<source_with_sympton>: [uid] @reverse .

Here is the query:

  qsyn(func: eq(sympton_name, "sympton_2")){
  sympton_handle
  sympton_name
  ~source_with_sympton{
      source_handle
      source_name
    }
  }

This will show a result as below.

Response:

{
  "data": {
    "qsyn": [
      {
        "sympton_handle": "sympton_2",
        "sympton_name": "sympton_2",
        "~source_with_sympton": [
          {
            "source_handle": "source_2",
            "source_name": "source_2"
          }
        ]
      }
    ]
  }
}

Please try it and let us know.
