How to update spreadsheet bound script using AppScript API? - google-apps-script

Question

I intend to update my bound script (destination) with contents from another script (source). I am trying the following code. It does not give any error, but do not modify the destination script either.
function getScriptSourceCode() {
var srcProjectId = "id of source project"; // Source project ID
var destProjectId = "id of destination project"
var baseUrl = "https://script.googleapis.com/v1/projects";
var accessToken = ScriptApp.getOAuthToken()
var srcName = JSON.parse(UrlFetchApp.fetch(baseUrl + "/" + srcProjectId, {
method: "get",
headers: {"Authorization": "Bearer " + accessToken}
}).getContentText()).title;
var content = UrlFetchApp.fetch(baseUrl + "/" + srcProjectId + "/content", {
method: "get",
headers: {"Authorization": "Bearer " + accessToken}
}).getContentText();
var url = "https://script.googleapis.com/v1/projects/" + destProjectId
+ "/content";
var options = {
followRedirects: true,
"method" : "PUT",
"muteHttpExceptions": true,
"headers": {
'Authorization': 'Bearer ' + accessToken
},
"contentType": "application/json",
"payload": JSON.stringify(content)
}
var response = UrlFetchApp.fetch(url, options);
}
}
Am i missing something?

Excuse me for the erroneous script. I modified the script little bit and now its working as desired. However it seems I have to run the script twice to get the desired result. Below is the working script.
function UpdateScript()
{
var destProjectId = "Destination project ID"
var srcProjectId = "Source Project ID"; // Source project ID
var baseUrl = "https://script.googleapis.com/v1/projects";
var accessToken = ScriptApp.getOAuthToken()
var content = UrlFetchApp.fetch(baseUrl + "/" + srcProjectId + "/content", {
method: "get",
headers: {"Authorization": "Bearer " + accessToken}
}).getContentText();
// Upload a project to bound-script project.
var response = JSON.parse(UrlFetchApp.fetch(baseUrl + "/" + destProjectId + "/content", {
method: "put",
contentType: 'application/json',
headers: {"Authorization": "Bearer " + accessToken},
payload: content
}).getContentText());
}
