Twitter Mobile Registration Content Bug

Noticed an interesting error message when going through the Twitter registration flow on the Safari browser on the iPhone.

Let’s start with the main Twitter landing page shown when the user goes to http://www.twitter.com:

When you click on Sign up, you will see the registration page:

Here’s the interesting part. If you leave all of the fields empty and click on Sign up, you will see the error messages for each field that you did not properly fill out.

All of the error messages make sense, except for the first one that is shown if the user does not enter their name. The text content is: translation missing: en, settings, name, hint

It’s pretty clear that instead of showing the correct error content, the app is showing some “code” content most likely from a configuration file. In this case, my guess would be that “en” refers to the English language, “name” refers to the text field for the error message, and “hint” refers to the name of the error content field that needs to be served to the user.
