I've just installed JOURNEYS and I'm at the first step of the migration process where it asks for session name and description.
When I click next it prompts me with "Failed to fetch"
Can someone help me get past this?
If I understand you correctly, you haven't uploaded a UCS or connected to a live BIG-IP system; if this is the case, you need to confirm that all the containers are running properly. It'd be helpful to provide more info on how you set it up.
