App Customization Specialist - Challenge 1 - List has no rows for assignment to SObject

Hello community!
I have a problem validating Challenge 1 on the Superbadge App Customization Specialist.
I have already created the new playground and installed the package correctly.
When trying to validate the challenge, the message appears
"Challenge 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.QueryException: List has no rows for assignment to SObject"
I've also used previous suggestions as well.
Could anybody help me?

Hi Carol,

Generally this exception is because of you are not getting any record in your SOQL query, which meet the where criteria so it's give error.

Please check the below article for more details.

Hello @Sai Praveen,
Thank you very much for the tips, but in this challenge I don't use coding, my development is totally declarative.
So, I can't apply your tips.
