Data validation superbadge

Hi Sanchi, 

From your screenshot, the matching rule looks active. I'd suggest checking that the Developer Name exactly matches the one required by the superbadge, as Trailhead validation is case-sensitive and expects an exact match. 

If the developer name and matching criteria are correct, try deactivating and reactivating the matching rule, then run Check Challenge again. 

If you're still getting the same error, try the superbadge in a new Trailhead Playground, as validation issues can sometimes be Playground-specific. If the problem persists, I'd recommend opening a Trailhead Support case with your matching rule configuration and the error message.
