JavaScript 'Post' Request Triggered an Error

I've been encountering a "Bad Request" error while attempting to make a POST request. I would greatly appreciate it if someone could point out where I may have gone wrong.

function mkSentiTopics() {
    dta['n_clusters'] = 3;
    $.ajax({
        type: "POST",
        url: "http://saxonydemoubuntu.southcentralus.cloudapp.azure.com/sentitopic",
        data: JSON.stringify(dta),
        dataType: "json",
        contentType: "application/json; charset=utf-8",
        success: function(response) {
            alert("success");
        },
        beforeSend: function() {

        },
        error: function(xhr, stats) {
            alert("error");
        }
    });
}

The variable "dta" is in the form of a dictionary.

// dta["sentis"] consists of a list of numbers
// dta["texts"] consists of a list of strings
// dta["n_clusters"] is an integer value.

It seems that the error is caused by a mismatch between the structure of the data being sent to the server and what the server expects, resulting in rejection. Without knowing the specific API requirements, it's difficult to provide a precise solution.

Based on the information provided in your post, I will make an educated guess and offer the following suggestion:

// dta["sentis"] should contain numbers
// dta["texts"] should contain strings
// dta["n_clusters"] should be an integer.

When using JSON.stringify(dta), ensure that the output exactly aligns with what the API anticipates. Remember that JSON recognizes boolean, array, object, string, and number data types. It's important to note that true !== "true", 1 !== "1", and so forth.

For example:

let dta = {                 
  sentis: [1, 2, 3, 4],     
  texts: ["a", "b", "c"],   
  n_clusters: 5             
}

console.log(JSON.stringify(dta, 0, 1));

If the API mandates that the root key "dta" must be included, or if the structure needs adjustment, modify your dta object accordingly.
