'Last_Day_of_Month__c' does not exist

This is about trailhead module: Advanced Formula / Troubleshoot formula errors.
I did create a field named,'Last Day of Month' under Case object and API name is also correct. However, the error message keep popping up said the field does not exist: The 'Last_Day_of_Month__c' does not exist.

I'd tried logging out and re-entering Trailhead but the error still occurs. Please advise. Thank you.

When I have faced this error last time, I was working on an ORG while the Trailhead was looking into another of my ORG.

Just make sure of the following two things.

1. Ensure that the API name of the field matches the exact requirement

2. Make sure that Trailhead checks the right ORG (do you see the tick mark against the right ORG?)

Open the Developer Console of your ORG to trace the log file generated by the Trailhead validation. This could shed more light on the issue.

I did the same checking as yours in the previous and no problem was found, i.e. API name is correct and the org is also correct.

No log file found from Developer Console.

Hi.
I had the same issue, and for some reason the field in case was created without security access to most profiles.
I think it happen when clicked quickly 'next, next...'.

To solve this simply provide field level security manually for the field
