# 3232 Running Script in the ElevateDB Manage Debugger Can Cause Invalid Request Error with Remote Sessions

---

Can't run an script.
I used this routine every day for last 10 days with 2.03.9 with no problems:
0. I'm working in a new major version of a production app
1. Every night, I have a fresh backup from my customer in my server
2. Every morning, I run attached script in order to get data updated for new version I working
3. When testing upgrading script, I manually restore last night version and running script again. With 2.03.15 I can't run script due to the following error:

"An invalid or unknown request was sent to the server"
