graph doesn't work after restarting sqlproxy

[dpeddi-gen]

Hello,

I'm on grafana v8.2.5 (b57a137acd). I'm using your plugin with an oracle database:

After restart of sqlproxy , graphs doesn't work.

This is the error from query inspector:

response:Object
timestamp:"2022-06-30T14:33:09.033+0000"
status:500
error:"Internal Server Error"
message:"Property 'dataSource' is required"
path:"/query"

To get graph working I need to go into the datasource and do a test + save

Thank you for your nice work!
