Might be a case of namespace declared in your org, I would suggest checking on newly created DEV Org.

i see exactly the same error since yesterday night (Nov/25th) and the error code changes a bit, but it's pretty much the same:

I can't progress after this.

I've also opened a Case for SFDC to find out what the problem is.
Kevin CaballeroKevin Caballero
I also got the same error on Nov 25th. I wonder if this is a system issue and will get resolved soon. I have already put in a ticket in with Trailhead support and will share what they reply once they reply.
Miguel FreitasMiguel Freitas
users in my org are also experiencing the same error and this is critical since this doesn't allow them to complete the superbadge 'Lightning Experience Reports & Dashboards Specialist' which they need to get in order to obtain a certain permission set defined internally - to qualify for the right to design reports and dashboards in the org:

Has anyone created another Dev org and tried to re-do challenge 3 to see if the problem still occurs then?

I'm having the same error on two superbadges, both are where they check the dashboards that were to have been created. I've also submitted a ticket. Both are playgrounds created specifically for the superbadge attempt.

Superbadge
Business Administration Specialist - Step 3

Superbadge
Lightning Experience Reports & Dashboards Specialist - Step 7
Gabriel McGinnGabriel McGinn

I tried again and the error has since changed to "Challenge Not yet complete... here's what's wrong:
Couldn't find a matrix report named 'Accounts by Market'."

No other changes were made.

Hi All @Miguel Freitas @Joshua Ayew-ew , Any update on this error? Still stuck at Lightning Experience Reports & Dashboards Specialist - Step 7. No response till now from salesforce support team for already submitted cases. If any update please do share.
Krishna NadoorKrishna Nadoor
Hi All!
Looks like I also have the same error, stuck on Step 7 on the Reports & Dashboards Superbadge. Get the error "There was an unhandled exception. Please reference ID: SYGRUMCK. Error: NoMethodError. Message: undefined method `[]' for nil:NilClass"

I've been using a fresh playground for this Superbadge.

It's interesting how a lot of people all have the same issue around the same time frame - I suspect it's probably a newly introduced bug that Salesforce need to resolve...

Experienced the same issue with two superbadges that I am trying to complete.

I have also tried to re-do both challenges and came to the same outcome and error. 

From what I can see everytime I create a dashboard and add a component to it - the error shows up when I check the challenge. But if I remove the component from the dashboard it comes up with the regular errors. 

I have also tried in both classic and lightning when creating the dashboard with component and it came to the same outcome. Tried other badges without any challenges related to dashboards and were able to complete it. But as soon as the dashboard + component comes up same issue nilclass etc error

Hi All,

I had the same issue with step 4 for the badge 'Reports & Dashboards for Salesforce Classic' where dashboard should be done.
If you need just to complete your badge (not to check your knowledge) please use the workaround that I found - just delete all components from dashboard saved with proper name. Then re-check challenge - it helped me.

Cheers,
Denis
Pablo Martín GarcíaPablo Martín García

I just tried to do that but the system shows the next error: "Couldn't find a component with the title 'Account Distribution'. " refering to the object that I just deleted...

Denis BlinnikovDenis Blinnikov
I guess it because you challenge requires components with specific names that checked in challenge. Means for cases with specific names for components resolution from SF team is required.
Rene De LeonRene De Leon
Hi Dennis,

I just deleted all the components from both my dashboards on Step #3 of the BAS Superbadge.

Now i see a different error: Challenge Not yet complete... here's what's wrong: Couldn't find a component with the title 'Account Distribution'.

This work-around didn't work for me. Still waiting for my SF Support Case to be fixed.

Regards,
Rene.
