Index was outside the bounds of the array

We use Studio 2017 API and Groupshare 2017 to create a project package with the pretranslate files and the analyzes report. Unfortunalty we got the error "Index was outside the bounds of the array". This error comes after it starts the analyze task.

It was working with SDL Studio 2015 after the upgarde to Studio 2017 we get this error.

If we use filebased memories it works without a problem. As soon we change to Groupshare we got this error.


What is the reason for this error. Thanks for helping.
