I get the following error when I run the code below. 'Field or property "Title" does not exist. undefined'

Anyone know why that is? The Title field does exist.

I'm also using Vue.js

<head>
    <script type="text/javascript" src="_layouts/15/sp.runtime.js"></script>    
    <script type="text/javascript" src="_layouts/15/sp.js"></script>

The internal name of the Title column is not always "Title". Which list template was used to create your list?

To find the internal name: Go to the list's properties page, in the Columns section, click your column's name. Check the end of the browser's URL to see the internal name.

For example, Created By is "Author".

...}&Field=Author

  • It says 'Title' _layouts/15/FldEdit.aspx?List=%7BBD6BB27D-4B03-4DF9-BFEE-16079F8A9C27%7D&Field=Title – OLA Apr 6 '19 at 1:26
  • Here's the weird part. As I comment out each set_item() line 1 by 1, the same error shows referencing each column – OLA Apr 6 '19 at 1:30

Your clientContext object does not have a URL.

var clientContext = new SP.ClientContext( yourSiteUrl );

or if running in a SharePoint page:

var clientContext = SP.ClientContext.get_current();

Otherwise, your code looks nearly identical to here: https://docs.microsoft.com/en-us/previous-versions/office/developer/sharepoint-2010/hh185011(v=office.14)

I don't know anything about the Vue.js library, so I can't help you there.
