Github API Create issue Markdown not rendering - github

Question

I am creating a GitHub issue via the API using a script.
var labels = [];
labels.push('proposal');
var body = \n*Title:* ' + title + '\n##Abstract: \n' + abstract;
var payload = {
"title": title,
"body": body,
"labels": labels
};
var options = {
"method": "POST",
"contentType": "application/json",
"payload": JSON.stringify(payload)
};
options.headers = {"Authorization": "Basic " + Utilities.base64Encode(handle + ":" + token)};
var response = UrlFetchApp.fetch("https://api.github.com/repos/"+org+"/"+repo+"/issues", options);
The issue is getting posted correctly to Github, except that the markdown is not rendered when I look at the issue in Github. It just shows up as ## and * instead of headers and italics. If I go ahead and edit the issue manually in Github and mark the headers using the visual editor, it puts in another # and then renders it correctly. How do I get it to show correctly using the API?

TL;DR
The markdown text in the body is not correctly formatted. Every markdown syntax character should be having whitespace around it, which in OP's case is absent.
Code :
var reqHeaders = new Headers();
reqHeaders.append("Authorization", "Bearer <token>");
reqHeaders.append("Content-Type", "application/json");
var rawBody = JSON.stringify({
"title": "Markdown not rendering due to malformed markdown text in request body ",
"body": "\n*Title:* This is some title \n## Abstract: \n And this is some abstract",
"assignees": [
"akmalick"
],
"labels": [
"bug",
"good first issue",
"help wanted"
]
});
var requestOptions = {
method: 'POST',
headers: reqHeaders,
body: rawBody
};
fetch("https://api.github.com/repos/<owner>/<repo>/issues", requestOptions)
.then(response => response.text())
.then(result => console.log(result))
.catch(error => console.log('error', error));
Below is the end result :
