I am following the exercise to Create Custom Controller Apex Class in Visualforce Basics -  I created the class and page ContactsListWithController - I added all the required code - I have a problem with the new action method - At the end the instructions say "Although the visual appearance remains the same, if you click the First Name and Last Name column headers now, they will change the sort order for the contacts list. Nice!" I do not get First Name or Last Name columns to click - I only get Last Name and when I click nothing happens - I am attaching screenshots of my code - I do not understand what I did wrong. Please check my code so can figure this out. Thank youscreen shot of my codescreen shot of my codescreen shot of my code

I cannot seem to pass this one simple challenge.  I've attempted it with my regular playground, my current DE Org, and setup a new DE with no  success.  The following message came through each time so I am assuming it's on Salesforce's side: "There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: CXHRJNMD"

Hi Friends,
I received an unexpected error while attempting to complete a challenge, "Create or Update a Contact"

Step not yet complete in xxxxxxxx@xxx.com
There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: SIAOTFWT

Any help is greatly appreciated.

Thank you.

HI Christoph,
The error is similar to GACK ID in salesforce. Most of the time, these go away when you try the challenge in a new playground or keep trying multiple times. If the error still persists, please use the below link to reach out to the Trailhead Support team so that one of the Engineers will get in touch with you and assist further.

Please mark this answer as best if it helps so that others facing the same issue will find it useful. Thanks
