Hi All,

This week, one of our customers got the following error when printing an SSRS report:

An item with the same key has already been added

Redeploying the report didn’t solve the issue. After restarting the AOS services and then redeploying the report, the issue was solved.
I’ve seen some forum/blog post about this, and I can confirm that this works.

This issue has popped up twice already, the previous time being a few months ago. No code was changed or anything, so I have no explanation for the error. Luckily, it’s easy to solve.

    Had the same. It was enough to restart the report server.
