hey everyone can you please help me on this ?

Hi Mohammed. have you built the LDM already or are you uploading a file to create the LDM?

i m uploading the file

Ok, do your headers have spaces in them?

yes they have like first name and last_name

Give me a min more and I can grab the documentation of how the file needs to be structured.

Hi Mohammed, are you uploading dates in your CSV file? This error could mean you have date data in your source file out of our supported formats. You can find supported date formats in the doc Leilani just sent.
