An unexpected error occurred while inserting Account records and we couldn't check your work. Make sure Account records can be inserted in this org, and click "Check Challenge" again. If this continues, contact the Trailhead Help team.

@Ananya D O Thank you for your feedback. I'm glad you made it. 

That is why in the previous message I advised 2 ways to solve the problem - to verify the Triggers and Validation Rules, and if not - to create a new Playground and execute it again.

I wish you success in your further study of Salesforce

Thanks all for your help!

Here's my findings..

@Ajaypreet Singh Saini This did help as I noticed in one of the opportunity fields

"Restrict picklist to the values ​​defined in the value set" was checked automatically as I chosed a global picklist. Later I tried editing it to uncheck the same but was unable to do. Please let me know if there's any option to uncheck this checkbox when we select global picklists.

@Mykhailo Vdovychenko Checked for validation rules and apex triggers, didn't have any.

@Divya Chauhan I finally tried in a new org where I deselected the checkbox that I mentioned earlier and it worked.

Hi, @Ananya D O

This is a common mistake that occurs because many previous Challenges were held on the same Playground. Most likely, in one of the previous Challenges, there was a task to create a Trigger or Validation Rule, and now it is affecting your current task. 

So, how can you solve this problem? There are two ways to resolve it. 

I. You can create a new Playground and complete this task there. 

II. You can go to the corresponding object and check if there are any related Validation Rules: 

1. Click Gear Icon --> Setup --> Object Manager 

2. Select Account object and from the left side menu click "Validation Rules": 

There should be no Validation Rules here. If there are any, you need to deactivate/delete them. 

Additionally, there might be a Trigger created. To view your list of Triggers, you can on the menu search field type "Trigger" and select "Apex Triggers":  

Here you should also not have any triggers. If there are any, they can affect your Account object.
