Parsing JSON output in Robot framework [TypeError: expected string or buffer]

I have a JSON output like this:

{
  "output": {
    "ParentKey": {
      "key": "9b92e663a66c0cc1",
      "id": "uid=26"
    }
  }
}

I'm trying to fetch the content of key, that is: 9b92e663a66c0cc1

Lets say ${output} has this JSON content/data..

This is the code I tried:

${values}=    Evaluate    json.loads($output)    json
${response}    Evaluate      json.loads($values['output']['ParentKey'])  json
${key}  set variable  ${response['ParentKey']['key']}
[Return]  ${key}

I'm using older Robot (less than v3.2)

However, I'm getting an error like this

Evaluating expression 'json .loads (RF_VAR_values ['output']['ParentKey'])' failed: TypeError: expected string or buffer

How do I fetch the key without getting above error?

Thank you!!!

*** Settings ***
*** Variables ***

${our_json}   { "output": { "ParentKey": { "key": "9b92e663a66c0cc1", "id": "uid=26" } } }


*** Test Case ***
Test JSON
  ${values}=    Evaluate    json.loads($our_json)    json
  Log To Console    ${values}
  ${key}  set variable  ${values['output']['ParentKey']['key']}
  Log To Console   OUR KEY: ${key}

outputs:
