Import and Export with Data Management Tools
Use the Data Import Wizard 


I traced the project to the trail head. However, the following error occurred.

User-added image

I made the lead according to the procedure and transformed the CSV file properly, but I do not know why I get an error.

Help me.

Hi,

Sorry for this issue you are encountering.

Solution 1:-
Please check following things.
  • You mapped the right fields with the once mentioned in the challenge.
  • Check the success file of the data you uploaded. 

Solution 2:-
  • Logged off and login in again if you already loaded the data into your Org.

If this doesn't work...I will suggest you try this in fresh DE org or a new playground, it might be the existing record causing the issues in your Org.

Hope this helps.

Kindly mark this as solved if the information was helpful.

Thanks,
Nagendra
