Warning "Failed to compile initial state with computed vars, excluding them: 2169" not understandable

[coproc]

Actually I need help with the following warnings / error messages. But maybe these messages can be improved at the same time.

Describe the Enhancement you want
Since a recent change in my code my reflex app does not start any more. The shown warnings and errors do not help me.

• Which feature do you want to improve? (and what problem does it have)
  I get the console message:

Warning: Failed to compile initial state with computed vars, excluding them: 2169

and the Server Error:

TypeError: Cannot read properties of undefined (reading 'map')

• What is the benefit of the enhancement?
  reflex app coders can solve such problems themselves

• Show an example/usecase were the improvement are needed.
  see above (my app-code is too long/complex to show)

Additional context
