I created the class - which works when testing it through Debug > Open Execute Anonymous Window , but when verifying this step I get this error:

Step not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.EmailException: SendEmail failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Either the plain text body or html body must be supplied.: [] 
Note: you may run into errors if you've skipped previous steps.

I've got an error from last challange in "Developer Console Basics":

"Challenge Not yet complete... here's what's wrong: 
Could not find the contact's name in the debug log. Be sure to run a query for your record, and to write your contact's name to the debug log using the System.debug() method."

But I'm sure that debog log include the correct lastname, first name as requested and use SOSL.

Does anyone else have the same issue?
