I’ve tried every solution I’ve seen on this topic, but nothing has worked so far.
Hi, @Ali OUANTER
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 three ways to resolve it.
I. Click Gear Icon --> Setup --> Object manager --> Oppurtunity --> Fields & Relationsships --> Close Reason --> Edit --> Picklist (Multi-Select) Options --> Deselect the checkbox “Restrict picklist to the values defined in the value set”.
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 Opportunity 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 Opportunity object.
III. You can create a new Playground and complete this task there.
To do this:
1. Login Trailhead Site
2. Open "Hands-On Orgs"
3. Click "Create Playground"
After waiting a few minutes, a new Playground will be created.
!!! Also too, make sure that all Challenges from this topic are completed in the same Playground. Each subsequent Challenge builds on the previous one.
