I am facing the issue on Mac as well.How could it be solved?

chinazhaoke97zk on 2 Jun 2020

I solved it by going to v2.25.8

manikantanallagatla on 2 Jun 2020

This might be related to changes here - https://github.com/Netflix/conductor/commit/167180ad517ef8d65679e2094ad3a63f4920cd5b#diff-90410c75a439e8a737f3bdc2c3794922R6-R9.
We will address this and release a fix soon.

@manikantanallagatla your suggestion worked perfectly:
After checking out tag/v2.25.8 then executing docker-compose up for serverAndUI it worked! I just want to study the platform, latest version was desired but not required for that purpose.
