@maciejmajek
I was testing agriculture demo while working on #325, but I got an error connected with rai_interfaces. Do you know what might be the reason?

The error occurs when the agent interaction is triggered

@maciejmajek I think the reason of the error is that in rai_interfaces.action.Task priority is a string, but in agri demo, it's set to be an int. I'll create a PR with a fix soon

Update: fixed in this commit
