Error in Data Import Wizard Trailhead Challenge

https://developer.salesforce.com/trailhead/force_com_introduction/data_management/data_import
I've tried 5-6 times now to use import wizard to import the file provided for the Data Management Module of Force.com Basics.  It just continues to give me an "There was a problem uploading the CSV file. Try again, or choose another file."  I've tried this on both a PC and a Mac, Chrome and Firefox and browsing to the file or drag and dropping the file, just get the same error every time.

Hi Deborah Orth,

I think "Lightning" is enabled in your org, then you will get the error i tested now. If u disable "Lightning " then you can forward to next step

I had the same problem, if you continue to have issues. I got passed it by using the "Import Accounts/Contacts" option just below the wizard option.

Thanks @all550 and @Micah Perry 10.  I do have lightening enabled in my org.  I also figured out the Imports Account/Contacts work-around and was able to get this completed shortly after logging this issue.

" Import Accounts / Contacts " work around option solved this for me.

Are we supposed to clean up the data first? There are duplicates and spelling errors etc in the data.

Sorry, I am in my way to the same challenge of Importing Data using the file suggested on the trail. Attached is my error after several tries. I do work on the Lighting version, but still not working. I tried eliminating the error attached by deleting the field "FNAME" on the CSV file. That let me go ahead but the report said that records are not found on my org ! 

Thanks in advanced for your help.

Hi Diego,

Please check which org you have set as the Default Org.  In your trailhead.salesforce.com lesson for Data Import wizard, under Hands-on Challenge, click on 'Hands-On Org Help' link and then set the Org where you Imported the data, as the Default Org.  I think Salesforce is looking for the records in a different Org.

For more information on How to Set the Default Org, go here:
https://force.desk.com/customer/portal/articles/2824652-hands-on-challenge-dropdown-menu-options?b_id=13478

Once you set the Default Org, come back and  "Check Challenge".

Hope this helps!

Hi Diego,

I had same issue like yours. I got it resolved when I changed to classic from lightening.

Hi there!

I have completed the data import successfully but, when checking the challenge, it stays loading. 

Any idea how to fix it?
