Hi,
i am working on apex super badge.On the second check which called "Synchronize Salesforce data with an external system"
i have this error:
There was an unhandled exception. Please reference ID: NQMGPJRH. Error: ArgumentError. Message: bad argument (expected URI object or URI string)
when i run my code in anynomus its working.
 

As I'm working my way through Trailhead to reassure myself, learn some new tricks, and train for ADM201, I have to admit I feel like I'm going all over the place. First we make a Fundraiser object, then WHOOSH we have to make a Garage? Oh okay, next challenge, we're making trails. Trails on Trailhead. I love it. And then Campsites, great, camping and hiking, all related. I'm feeling good.

A few challenges later? Project management! But only for a second because now we're talking role hierarchy for a sales organization. And by the time we hit workflows we're escalating cases and I haven't gone hiking in way too long. I'm making a Flow to create Opportunities, I haven't even gone outside! 

It'd be AMAZING if Trailhead gave me the feeling of actually creating something full featured, like the workbooks do. It's very distracting to be all over the map, and my schema is getting packed! The camping/hiking/trail app sounds like a lot of fun, and lets us as admins in training break away from the monotony of sales processes (especially when Trailhead isn't even actually teaching us those features!)
