How to right the correct code which will generate the Json output using my python Flask code in controllers connected to yml file in swagger directory

I am trying to write code for my openapi 3.0.0 which can generate the JSON output according to the yml specs I have written for my code, my Python Flask code is present in controller called default_controllers.py. It is basically open api generator by which I have to get values using my GET api I am building in yml through swagger editor.

My Code -->default_controllers.py present in controllers directory

from flask import Flask, jsonify, request
from flask import Flask, jsonify
from flasgger import Swagger, swag_from

app = Flask(__name__)
app.config['SWAGGER'] = {
    'openapi': '3.0.0'
}
swagger = Swagger(app)


@app.route('/calls/<details>/')
@swag_from('/home/teladmin/Desktop/python-flask-server-generated/swagger_server/swagger/swagger.yaml')
def calls(details):
    all_calls = {
        'totalCalls': [1000],
        'message': [200],
        'successfulCalls': [800],
        'failedCalls': [300],
    }
    if details == 'all':A
        result = all_calls
    else:
        result = {details: all_calls.get(details)}

    return jsonify(result)


app.run(debug=True)

Below is my yaml file which I have written using swaggereditor.io and generate python-flask zip using Generate Server tab
