I am working on the following Trailhead module:  https://developer.salesforce.com/trailhead/project/salesforce_developer_workshop/creating_apex_class

I receive the an following error message:
Execute Anonymous Error
Line: 9, Column: 1
System.EmailException: SendEmail failed. First exception on row 0; first error: INVALID_ID_FIELD, ID is invalid or you do not have access to the record.: [toAddresses, YOUR_EMAIL_ADDRESS]

My assumption is that I need to delete or overwrite the EMailManager but I can't seem to figure out how to to this.  Any help on what I should do in order to complete this module would be greatly appreciated.  

Hi Techies,

 

I am getting some problem during SFDC Plural label creation.Actually some time this input plural label is display but sometime it disappear.

 

I don't know exact problem of appear and disappear of this input field. If plural label is disappear and your custom object will be create then Deployment time it will create problem and display some error like

 

"Must specify a non-empty plural label for the CustomObject "

 

Please help me why it appear/disappear. Even i have latest version of Salesforce/Force.com.

 

Thanks in Advance

Rakesh
