Unexpected behaviour when saving user data.

[JuneOh710]

I'm having some trouble saving the experiment data where (1) the data would fail to save and (2) the program will not automatically advance to the next experiment in the container. This occurs for both JsPsych and custom experiments. Here is the code that I'm using to save the data:

For JsPsych:

const settings = {
    fullscreen: true,
    on_finish: function (data) {
        // Serialize the data
        var promise = new Promise(function (resolve, reject) {
            var data = jsPsych.data.get().json();
            resolve(data);
        })

        promise.then(function (data) {
            sendResults(data);
        })
    }

}

const jsPsych = initJsPsych(settings);
async function sendResults(results) {
    function handleErrors(response) {
        if (!response.ok) {
            throw Error(response.statusText);
        }
        return response;
    }

    fetch("/save", {
        method: "POST",
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({ data: results })
    })
        .then(handleErrors)
        .then(response => console.log("Request complete! response: ", response))
        .catch(error =>
            jsPsych.data.get().localSave('csv', 'cognitive_estimation_task_result.csv')
        );
}

For custom:

async function sendResults(results) {
    function handleErrors(response) {
          if (!response.ok) {
              throw Error(response.statusText);
          }
          return response;
      }

      fetch("/save", {
          method: "POST",
          headers: { 'Content-Type': 'application/json' },
          body: JSON.stringify({ data: results })
      })
          .then(handleErrors)
          .then(response => console.log("Request complete! response: ", response))
          .catch(error => console.log("We got an error: ", error));
}

What is the error in the console?

[JuneOh710]

I checked the console and there isn't an error message.
We would see the success logs when we run an existing experiment but we don't see any messages when we run one of our new experiments.

I need something to be able to help you - either the container pushed to a public registry with instructions to pull and run (and show me how to reproduce) or to see the error verbatim.

[JuneOh710]

I will get back to you with one of those by tomorrow (I need to get access to the containers).
