We are trying to make out, Http Callout to the endpoint and using "Named Credentials" to make endpoint URL (having the certificate attached).

Issue:- When callout happens it gives an error " "errorURI": "/rest/v1/LLP/crmmP/organization/12345678/service"," where Named Credentials are not taken as part of URI, any thoughts on this?

I receive this error when I check my challenge.


Challenge not yet complete... here's what's wrong: 
An account with a related opportunity did not calculate the correct potential value.

The task was to Create a rollup summary field that determines the potential value of the opportunities associated with an account.
Add a custom field to the standard account object that provides a rollup summary of the total expected revenue from all related opportunities.The rollup summary field should be labeled 'Potential Value' and have the Field Name of 'Potential_Value'. The resulting API name should be 'Potential_Value__c'.
The rollup summary should calculate the total expected revenue of all the opportunities related to the account.

Here is a snap shot of my work. Any suggestions as to why this is failing?



Thanks,
Darren
