Why is the below function is not returning value of Adddate in response?
code-
@app.route('/viewGrossMotorForm', methods=['GET','POST'])
def viewGrossMotorForm():
    session=Session()
    try:
        if(request.method == "POST"):
            if('Authorization' in request.headers):
                token= request.headers.get('Authorization')

                if not token:
                    return jsonify({'MSG':'Token is missing'})
                data = jwt.decode(token,app.config['SECRET_KEY'], algorithms=['HS256', ])
                if(data):
                    request1= request.get_json()
                    pid = request1.get('pid')
