Troubleshooting: Error message "Cannot write a value to a ko.computed unless you specify a 'write' option"


Explanation

This error can occur when attempting to Move or Copy files in SharePoint in the browser. The error message is similar to:

 Cannot write a value to a ko.computed unless you specify a 'write' option. If you wish to read the current value, don't pass any parameters

This error is intermittent and seems to be related to browser caching. It occurs most often in Chrome or Safari.


Troubleshooting

Clearing the browser cache often resolves this error. Holding down Ctrl + r   OR    Function key [Fn] + [F5] may work. If not, a manual clearing of the browser cache may be required.

Users can also try using a private browser window or incognito mode.
