Editing activities fails with "Invalid request"

Expected behavior and actual behavior

Activities should be editable from the UI without a server-side request error. Currently, attempting to edit and save an activity fails with an "Invalid request" error message.

Steps to reproduce the problem

1. Open any existing activity.
2. Edit the activity.
3. Save the changes.
4. Observe that the request fails with an "Invalid request" error message.

@RussH can you verify this bug?

I can no longer reproduce this issue on the current master branch after forcing a hard reload and bypassing cached JavaScript assets in the browser.

The observed behavior was caused by stale client-side assets, so the browser was still executing an outdated js/lib.js version. After reloading with cache disabled, the affected AJAX requests worked again.

Closing as not reproducible on current master.
