bug import errors but no xml file generated

Dec 5, 2012 at 11:52 PM

I am running into an issue where I am migrating bugs from excel (pulled out of another system into a spreadsheet with columns matching TFS).  I map all the data through the app and it starts to import but about halfway through it stops each time with the below error:


  Failed Migrate Work Items There was an error generating the XML document.
  Failed Publish Report No Workitems are migrated

Since no report is generated I am at a loss as to what the problem is.  Any ideas?
