Hi ,

I added a simple route to the routes.py file

@rest_api.route('/hellos')
class TestProcedure(Resource):
	def get(self):
		hello =  {"hello": "test"}
		return jsonify(hello)

I also tried

@rest_api.route('/hellos')
class TestProcedure(Resource):
	def get(self):
		hello = "lol"
		return {"success": True}, 200

I always get this error i have to reload my page 2-3 times to get the actual result
