Trailhead: My Challenge Won't Validate, and I'm 100% Sure It's Right

Is this happening to you? You're 100% sure you've done a Trailhead challenge right, but it just won't validate?

So here's the deal. We're doing a real-time API call to check your work, and sometimes, there might be existing configuration or code in your Developer Edition that interferes with our check, causing it to fail.

The best thing to do if you're 100% sure you're right is create a new Developer Edition and do the challenge again.

But wait, what about my badges?

No worries! Logging into Trailhead is a two-step process. Check out this image.

Trailhead: My Challenge Won't Validate, and I'm 100% Sure It's Right

In step (1), you tell Trailhead who you are. This is where your badges are stored. You can use your production username or any Developer Edition username for this step.

In step (2), you tell Trailhead where you're doing the challenge. This must be a Developer Edition.

Okay, I got the new DE. Now what?

So, just stay logged in at (1), and make a new Developer Edition to log in at (2). Do the challenge in the new Developer Edition and check it.

If it passes, it was probably something funky in your old DE. If it fails, time to revisit your challenge! Read the instructions again and make sure you didn't miss any steps.

But why would this happen?

It could be your DE is older, or it could be you've done some additional config or customization that is interfering with our check. 

Good luck!

    If somebody still has the problem - i encountered this while try to solve the salesforce trailhead and entering geolocation coordinates for a contact - try entering the coordinates/geolocation latitude longitude with a comma instead of a dot : 37.923824 ----> 37,923824
