Click on group members' name ends you in nowhere

[HannahSonntag]

On prod(!)

• Go to a group eg. https://sdash.sourcedata.io/group/5
• Click on any members name eg. Thomas in this exmple:
• expected: see Thomas' profile
• reality: black page and 404 error

profiles are accessible though when clicking on the authors name and 'view full profile' on the panel (see screenshot below)
