Recently in our project we were getting this error continuously while creating a user in CRM using SDK. The code basically reads the user data from a text file and creates the record in CRM.
Googled a lot about the error and tried all the resolutions available. But nothing solved the problem. Also the problem was not occuring for all users but some of the user’s data. Hence we thought that the error might be because of data and nothing to do with the code.
Voila!. Our guess was right. for some of the user’s data, first name and the last name was not coming. Since CRM derives the Fullname of the user from the First, Last name, we were getting this error.
However had to say that the error message is quite misleading.
However thought of sharing since this might be of help for others getting similar error.
Hope this helps!
