Uncaught TypeError: C.createPostQuery is not a function

RobertBossio — Mon, 09 Aug 2021 18:32:10 GMT

I'm trying to save a layer created on client web application using JavaScript API 4.20 to the user's portal. I'm using portal.user.addItem function but get error, "Uncaught TypeError: C.createPostQuery is not a function".

Any examples of saving a layer to user's portal using portal.user.addItem? I can successfully read user's layers from the portal, and save one back (changing some values to make it unique). Is the issue that the layer is created on the client (FeatureLayer) and then saved to the portal? Any way of doing this with the JavaScript API?

Any info appreciated.

Hello Robert, were you able to figure out what was wrong here? I currently have the same issue. I was able to save a new item at some point although it was not sending the geometries with it. Since then I've implemented some other features into my project but now that I've come back to this I get this error.

Hi Richard - I've since abandoned how I was doing that. The correct approach (with help from an Esri developer) to save a layer/map from Web application is to follow these 3 steps, calling the Esri RESTful API:

1. Create Feature Service (https://developers.arcgis.com/rest/users-groups-and-items/create-service.htm)

2. Add to Definition (to feature service) - (https://developers.arcgis.com/rest/services-reference/online/add-to-definition-feature-service-.htm)

3. AddFeatures (adds points to definition) - (https://developers.arcgis.com/rest/services-reference/enterprise/add-features.htm)

Note: You have to be logged-in to an existing Esri account (ArcGIS Online or an Enterprise instance)

Hope this helps.

Thank you for the update. I will give that a try. Have a good evening.

I was finally able to get the service created through the method that you shared but I am a little lost on what the URLs should look like for the other two steps. Can you provide any insight on those?

Hi Richard - sorry for the delay as I'm just now noticing your request. Here's example URLs. Hope this helps if you haven't already figured it out:

1. CreateFeatureLayer

var createParameters = {

const settings = {

};

$.ajax(settings)
.done(function (response) {
try {

}
} catch (error) {
return reject(error);
}
}).fail(function (xhr, status, error) {

});
} catch (error) {
return reject(error);
}

2. addToDefinition

var layerDefinition = {

3. Add Features to Layer

$.ajax(settings)
.done(function (response) {
//need to handle for an error coming back as string
let errorMessage;
try {
let responseObj = $.parseJSON(response);
if (responseObj.error)
errorMessage = responseObj.error.message;
} catch (error) {
//display error
}
})
.fail(function (xhr, status, error) {
//display error
});
