How to fix [Cannot read property 'Yb' of undefined]

Hi all,

we have developed from since almost a year ago a visualforce page leveraging on Lightning. And using it in all our development, full sandbox, and production environment.
today in our full sandbox environment it has appeared the following error message:
Something has gone wrong. Action failed: c$MatchComponent$controller$init [Cannot read property 'Yb' of undefined] Failing descriptor: {c$MatchComponent$controller$init}. Please try again.
the really strange fact is that all the enviromnts are alligned in terms of code for page and classes.

is there anyone who have experienced somithing similar?


I think you controller is trying to set value of any attribute which is not defined in component.
