Axios POSTing data records to Dynamo, but unable to Axios GET request to find – Javascript/Typescript

I have the following code for POSTing a record via axios to my DB, and then I would like to search for said record by its ID match as well as list all the latest records.

I have confirmed, via checking Dynamo, that the record gets added to the DB but cannot get it to appear when I look for it via the GET /search.

It makes me wonder if I’m somehow making a mistake.

I know that my database has 6000+ records of this same type, so I could just be getting unlucky (as I have not yet included pagination in my queries)… but I’ve tested this about 50 times with 0 retrieval success via the query vs running the same POST and GET via Postman and having about a 50% success rate.

test('post result then search for presence', async () => {
    const trafficAnalyticMessage = buildTrafficAnalyticMessage();

    const result = await axios.post(messagesUrl, trafficAnalyticMessage, {
      headers: {
        'x-api-key': 'redacted',
      },
    });

    const message = result.data as dataMessageApi.Message;
    logger.log(`Message ${util.inspect(message)}`);
    // logger.log(`Result ${util.inspect(result)}`);

    const results = await axios.get(searchUrl, {
      headers: {
        'x-api-key': 'redacted',
      },
      params: {
        type: 'analytic',
        subtype: 'traffic_volumes',
        startTime: 1,
      },
    });

    logger.log(
      'Attempting to search for message with id: ' + JSON.stringify(message.id),
    );

    const messages = results.data as dataMessageApi.Message[];
    const found = messages.find((m) => m.id === message.id);

    logger.log('Message returned from search: ' + JSON.stringify(found));
    // expect(found).toBeDefined();

    let date: string;
    // log length, first and last msg id
    logger.log(`Length of search response:  ${messages.length}`);
    // 1
    logger.log('First ID:  ' + JSON.stringify(messages[0].id));
    date = new Date(messages[0].timestamp!).toUTCString();
    logger.log(`First timestamp: ${date}`);
    // 2
    logger.log('Second ID:  ' + JSON.stringify(messages[1].id));
    date = new Date(messages[1].timestamp!).toUTCString();
    logger.log(`Second timestamp: ${date}`);
    // 3
    logger.log('Third ID:  ' + JSON.stringify(messages[2].id));
    date = new Date(messages[2].timestamp!).toUTCString();
    logger.log(`Third timestamp: ${date}`);
    // 4
    logger.log('Fourth ID:  ' + JSON.stringify(messages[3].id));
    date = new Date(messages[3].timestamp!).toUTCString();
    logger.log(`Fourth timestamp: ${date}`);
    // Fifth from last
    logger.log(
      'Fifth from last ID:  ' +
        JSON.stringify(messages[messages.length - 5].id),
    );
    date = new Date(messages[messages.length - 5].timestamp!).toUTCString();
    logger.log(`Fifth to last timestamp: ${date}`);
    logger.log(
      'Fourth from last ID:  ' +
        JSON.stringify(messages[messages.length - 4].id),
    );
    date = new Date(messages[messages.length - 4].timestamp!).toUTCString();
    logger.log(`Fourth from last timestamp: ${date}`);
    logger.log(
      'Third from last ID:  ' +
        JSON.stringify(messages[messages.length - 3].id),
    );
    date = new Date(messages[messages.length - 3].timestamp!).toUTCString();
    logger.log(`Third from last timestamp: ${date}`);
    logger.log(
      'Second to last ID:  ' + JSON.stringify(messages[messages.length - 2].id),
    );
    date = new Date(messages[messages.length - 2].timestamp!).toUTCString();
    logger.log(`Second to last timestamp: ${date}`);
    logger.log('Last ID:  ' + JSON.stringify(messages[messages.length - 1].id));
    date = new Date(messages[messages.length - 1].timestamp!).toUTCString();
    logger.log(`Last timestamp: ${date}`);

    expect(result).toBeDefined();
    expect(result.status).toBe(201);
  });

This is the output I am getting:

Any help would be greatly appreciated.

**Also, please can you advise me how to add the GET as a .then result of the POST? Or a promise or some kind of 2-part resolution? I have had great trouble figuring out how that works. I’m new to this kind of work.

Thanks so much!!**
