Hi Aditya,

Please note that Questions about how to pass Trailhead challenges are not on topic, because these challenges are intended to be independent demonstrations of your abilities.Trailhead Help (https://trailhead.salesforce.com/en/help?support=home)can provide assistance for situations where Trailhead does not appear to be functioning correctly. You can reach out to them if this is the case.

Thanks!

Hi Abhinav, 

May be I worded it incorrect.. I am not looking for a solution. If you look at the problem - the error message is very obvious. 

I am trying to figure out if it could be a Trailhead issue and if others have faced the issue.

If you are planning to buy a water purifier for your home, then the first thing you need to know is the quality of the water supply in the house. Check this https://bestwaterpurifierreviews.in for more details.

Hi,
Please share your error Here.
maybe it should not be String and here you use this as a String Value :
customField.field = 'customField__c ';
make sure the value dataType and put that type value only.

if you have any query please comment.
