Google Apps Script to Create Confluence Page -- Results in Status Code 500 - google-apps-script

Question

Note: I also posted this question on the Atlassian forum here:
https://community.atlassian.com/t5/Confluence-questions/Google-Apps-Script-to-Create-Confluence-Page-HTTP-500-Error/qaq-p/1039040#M66094
I'm reaching out to a larger audience here on SO.
I'm using the following google apps script code in a Google Sheet to create a Confluence page:
headers = {"Authorization" : "Basic " + Utilities.base64Encode(user + ':' +
pswd), "Content-Type": "application/json"};
url = "https://confluence.asdf.com/rest/api/content/";
var params = {
"method":"POST",
"headers":headers,
"muteHttpExceptions": false,
"type":"page",
"title":newTitle,
"space":{"key":"DOC"},
"body":{"storage":{"value": "<p>This is <br/> a new page</p>" },
"representation":"storage"}
};
var createResponse = UrlFetchApp.fetch(url, params);
However, when I submit the request, I receive this response:
Request failed for https://confluence.atlas.asdf.com/rest/api/content/
returned code 500.
Truncated server response: {"statusCode":500,"
message":"<?> No content to map to Object due to end of
input","reason":"Internal Server Error"} (use muteHttpExceptions option to
examine full response)
I realize there are curl samples out there which I've seen but do not help me.
What am I doing wrong?

I modified the code as you suggested:
headers = {"Authorization" : "Basic " + Utilities.base64Encode(user + ':' + pswd) };
var payload = {
"type": "page",
"title": newTitle,
"space": {"key": "DOC"},
"body": {
"storage": {
"value": "<p>This is <br/> a new page</p>"
},
"representation": "storage"
}
};
var params = {
"method": "POST",
"headers": headers,
"muteHttpExceptions": false,
"payload": JSON.stringify(payload),
"contentType": "application/json"
};
var createResponse = UrlFetchApp.fetch(url, params);
I receive the same error as before.

How about this modification?
Modified script:
Please modify params as follows and test again. From the error message in your question, the request body was put in the property of payload.
var payload = {
"type": "page",
"title": newTitle,
"space": {"key": "DOC"},
"body": {
"storage": {
"value": "<p>This is <br/> a new page</p>"
},
"representation": "storage"
}
};
var params = {
"method": "POST",
"headers": headers,
"muteHttpExceptions": false,
"payload": JSON.stringify(payload)
};
Note:
This modification supposes that each value in payload and headers is correct.
"Content-Type": "application/json" in headers can be also put in params as "contentType": "application/json".

I cannot test this modification. So if this didn't work, can you provide the error message? I would like to think of about the issue.
Edit:
From the official document, it seems that the property of body is "body":{"storage":{"value":"<p>This is a new page</p>","representation":"storage"}}}. So please modify as follows.
Modified script:
headers = {"Authorization" : "Basic " + Utilities.base64Encode(user + ':' + pswd) };
var payload = {
"type": "page",
"title": newTitle,
"space": {"key": "DOC"},
"body": {
"storage": {
"value": "<p>This is <br/> a new page</p>",
"representation": "storage" // Modified
}
}
};
var params = {
"method": "POST",
"headers": headers,
"muteHttpExceptions": false,
"payload": JSON.stringify(payload),
"contentType": "application/json"
};
var createResponse = UrlFetchApp.fetch(url, params);
Note:
In my environment, I could confirm that the result was the same with the result from the official sample script. If this didn't work, please confirm each value of payload and headers, again.
