I am trying to get determine if I am passing an object key value pair to a get request in a python rest api. I have the following:

@app.route('/', methods=['GET', 'DELETE', 'POST'])
def profits():
    if request.method=='GET':
        if 'listname' in request.json:
            print 'inside listname == True!!!'
            conn = psycopg2.connect(database = "profitnloss3", user = "patientplatypus", password = "Fvnjty0b")
            cur = conn.cursor()
            sql = 'SELECT * FROM ledger WHERE listname = %s'
            params = (request.json['listname'])
            cur.execute(sql, params)
            conn.commit()
            data = cur.fetchall()
            conn.close()
            return jsonify(data)
        else:
            print 'inside listname == False!!!'
            conn = psycopg2.connect(database = "profitnloss3", user = "patientplatypus", password = "Fvnjty0b")
            cur = conn.cursor()
            sql = 'SELECT * FROM ledger'
            cur.execute(sql)
            conn.commit()
            data = cur.fetchall()
            conn.close()
            return jsonify(data)

Which I call on my front end with an axios call

  axios({
          method: 'get',
          url: 'http://localhost:5000/',
          headers: {
            'Content-type': 'application/json'
            },
          data:{
            'listname': this.ledgername
              }
        })
        .then((response)=>{
          console.log('this is the response from the python server on a get request of listname ', response);
        })
        .catch(error=>{
          console.log('here is the error on a get request from the python server of listname ', error);
        })


But the error I get is:

TypeError: argument of type 'Request' is not iterable





My google fu is failing me, but I suspect that python is somehow not allowed to look through the request list by looping through it. However I have seen other people on stackoverflow say that similar things will work. What am I not seeing?
