Flask response: list doesn't work, dict unhashable, tuple malformed?

Question

I have a function through which I am trying to return a series of houses, filtered by a price.

Here is the function:

@app.route('/calcprice', methods=['GET', 'POST'])
def calcprice():
    price = '120000'
    if request.method == 'POST':
        testVal = request.form
        price = str(testVal['Income'])

    # The view function did not return a valid response
    res = [d for d in output_dict if d['ListPrice']<=float(price)]

    # gets an unhashable type
    it = iter(res)
    res_dct = dict(zip(it, it))

    # The tuple must have the form (body, status, headers), (body, status), or (body, headers).
    res_tpl = tuple(res)

    return res

When I go with "res", I get the commented error. When I go with "res_dct" as the response, I get that commented error. Same with the tuple and its commented response. I am changing the return to return the correct given variable.

res itself is a list of dictionaries, here is a snapshot:

{'MLSNumber': '9504716', 'ListPrice': '659849.00', 'BedsTotal': '4', 'MLSAreaMinor': 'Greenways At Sand Creek', 'StreetNumber': '3819', 'StreetName': 'Ivy Hill', 'PostalCode': '80922', 'TaxAmount': '200.00'}, {'MLSNumber': '4426383', 'ListPrice': '1500000.00', 'BedsTotal': '4', 'MLSAreaMinor': 'Keene Ranch', 'StreetNumber': '3231', 'StreetName': 'Castle Butte', 'PostalCode': '80109', 'TaxAmount': '4967.00'}

Here, too, is the div I am ultimately injecting the information into:

<div class="row">
        {% for item in purchase %}
        <div class="col-lg-12">
            <div class="card">
                <div class="card-body">
                    <h5 class="card-title"> MLS: {{ item['MLSNumber'] }}</h5>
                    <p class="card-text">List Price: {{ item['ListPrice'] }}</p>
                </div>
            </div>
            </div>
        {% endfor %}
        
    </div>

It works with the first list until I update the variable price via an input field. Then the error about the valid response kicks in.

Where(s) am I going wrong?
