I did as the challenge requires but the Challenge is not completed. I'm getting the below message. I replaced with original code, fit the whole code on line 13 etc. I exhausted all different options but still challenge would not complete. I'm even getting the email successfully.

Challenge Not yet complete... here's what's wrong: 
Could not find an execution checkpoint for line #13. Make sure you set the checkpoint on line #13 and execute the EmailMissionSpecialist class before checking this challenge.

Any ideas anyone?

Hey did you figure this out, Binoy? I get the the same error. Even though I finished all the steps.
Aaron EdelmanAaron Edelman
Same issue with me.  The code, as copied from Trailhead, has the Messaging.SingleEmailMessage on line 12, not 13.  Even moving the code down one line produces the same error as Binoy.

The checkpoint not showing up is probably a bug in the Developer Console. I couldn't get it to work in Safari or Chrome. If you are just looking to score points on the challenge just put a new line on Line Number 2, as shown in the picture above. This should put  
Messaging.SendEmailResult[] results = Messaging.sendEmail(

on line 13. Doing this and then executing once will give you the points. However, if you actually want to see the heap as they want you to, under Debug, uncheck 'Show my current checkpoints only' and you'll see the checkpoints.'

I think the line 13 code is distributed across 13 and 14. Making them appear on single line did the trick for me

Thank you Dinesh Gajwani for your input. It worked as a put a new line on Line 2 as show in above picture. Also, as Vasanth mentioned I put the whole code on Line 13 and it worked. 

Thanks so much for your effort to answer this. Appreciate it!!!

@ Avani and Aaron- I hope this works for u also

Hey Binoy, Dinesh and Vasanth, it works! Thanks so much for your input.

Hi Binoy, Dinesh and Vasanth, it worked! Thanks so much for your input.  Also please note that the expected behaviour of the "Debug - show current check point only" check box needs trial and error to understand.

Hi guys, just Save your apexcode before execute it, unless server side, does not know the checkpoint and doesnt allow you to finish this challenge
Tracy DyeTracy Dye
I have no idea what Cagkan means.  I have tried to do what you all have said and I am getting the same error.  
Tracy DyeTracy Dye
Fixed it- make sure you save the file you change.  Simple but I forgot.  If it has an asterisk in the file name, it's not saved.

Saving the code on line 13, worked for me! Thanks Sfdc Vasanth

Hi all,

i`m also stuck on this and none of the above suggestion does not work for me. For some reason when i put a checkpoint location on row 13 and execute the code nothing is showing up in my "Checkpoints" section. If I uncheck the "Show my current checkpoints only" it shows me some old checkpoints, but nothing for line 13. I assumed there is a limit of 5 checkpoints, just like there`s a limit of 5 checkpoint locations. However while this checkbox is unchecked even if I go an clear the checkpoints from the menu nothing is happening. Any ideas?

I was able to force the checkpoints to appear in the console by removing comments and white space between the lines. I also placed 5 checkpoints for good measure:

Add extra line on 12 and Making line 13-14 appear on single line works for me.

To add the actual checkpoint, you have to actually click on the left side where the numbers are, so in this case Line #12 if that's where they want the checkpoint, and then the red dot will appear.

I still have the error ===> We can’t find an execution log that shows a checkpoint at line #12. After you set the checkpoint, make sure you execute the EmailMissionSpecialist class before you check this challenge.I tried 2 things: 1)Put a space on line 2 .     2)line 12 ===>  Messaging.SendEmailResult[] results = Messaging.sendEmail( new Messaging.SingleEmailMessage[] { mail });                                  still doesn't work.
