HI, Trailhead won;t give me credit for passing this trail but here is what I need to warn you about:

When perfomring the trailhead exercise at:
 https://trailhead.salesforce.com/en/content/learn/modules/api_basics/api_basics_bulk 
Make sure that you :

• Put double quotes around the bulk input CSV file records  that you need to upload in the workbench PUT body.
• Unquote the Name API field value that is in the workbench PUT body.
• Verify that you see all records Process in SF UI : Setup->Bulk Data Load Jobs (It should say "Records Processed: 500". )

I have enclosed a screen scrape of a perfectly uploaded set of 500 records based on the Bulk Apex Jobs page but Trailhead still won't give me credit after doing these steps. See below:
I just wanted to let everyone know who is taking this trail because the figure for loading the data is incorrect and you will waste valuable time wondering why the batch load is failing. Thanks
