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,
Sonia Varney
