There was an error in evaluating the test script: SyntaxError: Unexpected token ':'

问题

Im using Postman for the first time (newbie) with testing out a Flask App that accepts Json data and Postman keeps giving me this error There was an error in evaluating the test script: SyntaxError: Unexpected token ':' but my Flask App seems ok. The Flask app accepts the Json and either returns a 200 or 400 and that seems to be working fine...

This is the Json I am sending to Flask thru the Postman console: {"Date": "2020-13-16T13:37:22.501743", "MeterReading": 5}

Anything worrisome?? Any tips greatly appreciated..

In Flask I can save the data to sql which seems to be working OK 200 response. 127.0.0.1 - - [17/Jun/2020 11:39:24] "[37mPOST /dataear HTTP/1.1[0m" 200 -

UPDATE FLASK APP CODE

from flask import Flask, make_response, request, render_template, jsonify, make_response
import pandas as pd
from sqlalchemy import create_engine
from pandas.api.types import is_string_dtype
from pandas.api.types import is_numeric_dtype

app = Flask(__name__)

@app.route('/dataear', methods=['POST'])
def getdata():

    r = request.get_json()
    if r.keys() == {'Date', 'MeterReading'}:
        try:
            df = pd.json_normalize(r)
            df = df.set_index('Date')
            #print(is_string_dtype(df.index))
            #print(is_numeric_dtype(df.MeterReading))
            if is_string_dtype(df.index) and is_numeric_dtype(df.MeterReading):# checker to verify MeterReading is numerical

                engine = create_engine('sqlite:///save_pandas.db', echo=True)
                sqlite_connection = engine.connect()
                sqlite_table = "OutsideTemp_MeterReading"
                df.to_sql(sqlite_table, sqlite_connection, if_exists='append')
                sqlite_connection.close()
                print("Data saved to sql!")
                return 'OK', 200
            else:
                print("rejected incorrect meter data unable to save data to SQL")
                return 'Bad Request', 400
        except:
            print("rejected incorrect date format unable to save data to SQL")
            return 'Bad Request', 400
    else:
        print("rejected incorrect keys for incoming json data")
        return 'Bad Request', 400
