Hello,
You are "expecting" quite a lot here. Per the rules of engagement for SCN, you should first show what steps you have done to search for this information yourself. This is a necessary step before posting questions in this forum.
Please reply back when you can show what you have done to try and figure this out for yourself.
Usually when you get a 500 error, the problem is with the external storage solution and you would need to contact them.
Regards,
Karin Tillotson
