Scheduler has limitation of 4000 characters
I have a flow which handles hindreds of servers succesfully when ran manually . Same flow while we try schedule does not get scheduled giving attached message . After trying multiple times the issue is with number of server names I mention at teh server list field .
Anyway to come over this limitation .
We have scase opend with HP and there is no solution yet .
You can workaround this limitation by providing the entire server list input in a file.
In this way OO will allow you to schedule the flow, read the content of the file, populate your server list and execute successfully the scheduled flow.
Hope this helps!
