Storing PDF files to SharePoint -> error

[gp_oconnor]

I have a connection to SharePoint, account is an owner of the site.  Trying to write PDF files to SharePoint site:

Error:

I have checked the parameters and the connection.

Does the connection need to have admin rights to write files?  Does default not suffice?  Or does this not work with site IDs and it needs the drive ID?

Any assistance would be appreciated.  Thanks.
