Issue in 2018.1, when we start debugging it shows message "Cannot start a job in 'debug' mode for a non-development robot"

if you don`t have Development license on Orchestrator, you ll have to disconnect from robot tray then use Debug

In 2017.1 it used to work together though. Alas, an extra step to remember but I probably will get used to that soon.

its a change in how robot types from Orchestrator work with Studio. but things may change in the future for community users, we are looking for a solution.

Thanks for clarifying. Much appreciated.

It’s our fault and we’ll revert back in the next update so that non-prod will still have debug.
However, medium term, you should split your non-prod licenses into dev & non-prod.
