Graphql query constructing in python

Question

payload = """ query GetOrders($num_els: Int, $created_at: String, $cursor: String) {
              orders(first: $num_els, query: $created_at, after: $cursor) {
                edges {
                  node{
                    email
                  }
                }
              }
            }"""

I try to send a simple query. The $cursor field can be empty.

variables = {'num_els': num_elements, 'created_at': f'created_at:>2022-01-10', 'cursor': None}
r = requests.post(constants['SHOPIFY_URL'], headers=headers,
                          json={'query': payload, 'variables': variables}).json()

However this gives me the

[{'message': 'Parse error on "query" (STRING) at [1, 2]', 'locations': [{'line': 1, 'column': 2}]}]

Even if I discard the a bit complicated part with $created_at , the problem continues. Do you have any suggestions?
