We have a few users testing importing projects from MS Project to Portfolios using the MS Project add-in.  When trying to upload a MS Project plan (.mpp) to Portfolios, users are experiencing an error that I’m not sure how to troubleshoot. 

“-General Failure: Unable to update projects with tasks:  Index was out of range. Must be non-negative and less than the size of the collection .

Parameter name: index”

 

Anyone have any tips on what could be causing this error? 

 

Thank you,

This error usually pops up when the 'Web Service Access' feature isn't enabled for the user.
Here's how you can fix it:

  1. Go to Administration > Users and Roles > Configure Users.
  2. Find the user who is encountering the error.
  3. Click on the role assigned to that user.
  4. Check the features enabled for that role and make sure 'Web Service Access' is turned on.

I hope this information is useful!
