Can't save a webmap with code from sandbox example using seperate custom Javascript file

dtstopper

Hello,

I'm trying to save a webmap to my portal but I get the error below when trying to save it.

Error: The item does not exist yet and cannot be updated

I've tried both the update and save new code and neither works.  My sample code is below.

I have tried both a dynamic and hard coded link.  

// item automatically casts to a PortalItem instance by saveAs
const l_title = document.getElementById("webMapTitle");
const item = {
title: l_title.value
};

//// Setting authMode to immediate signs the user in once loaded
//portal = new Portal();
//portal.authMode = "immediate";
//// Auto should sign you in automatically
//portal.authMode = "auto";

// Update properties of the WebMap related to the view.
// This should be called just before saving a webmap.
//portal.load().then(function () {
map.updateFrom(view).then(() => {
map.saveAs(item)
// Saved successfully
.then((item) => {
// link to the newly-created web scene item
const itemPageUrl = `${item.portal.url}/home/item.html?id=${item.id}`; //OG itemPageURL setting
//const itemPageUrl = "https://www.arcgis.com/home/item.html?id=a24a038265eb4f3584451292c70d68ad" 
const link = `<a target="_blank" href="${itemPageUrl}">${l_title.value}</a>`;

alert("Successfully saved as <i>${link}</i>");
})
// Save didn't work correctly
.catch((error) => {
if (error.name != "identity-manager:user-aborted") {
alert("Error: " + error.message);
}
});
});

 

 

I've also tried the to save using a portal also

////Save a new Webmap
portal.load().then(() => {
 map.updateFrom(view).then(() => {
 map.saveAs({
 title: l_title,
 portal: portal
 });
 });
});

 

Can anyone provide a working example of how to save to one's portal or get the portal to queue a log in window for me to authenticate?  It works when I query portal items, but now when I try to save maps.  The sanbox works on the ESRI server, but not in my local code.

Any help is appreciated, thank you!

There was no issue with the code, it turns out that when you assign an API Key to your code when trying to save a map it will not work and give you a misleading error message saying the item doesn't exist.  If you are using an API Key from ESRI in your code, remove it from your map creation and saving code.  This resolved it for me, hope this helps someone else.
