Hi mmamrot
An interactive session is needed for running UI tests however how we run that session can differ.
How are you running the session?
What options are configuring to run the interactive session
For example, have you specified credentials for the interactive sessions?
If you are unsure please check both of these docs as it should point out how to configure this successfully
