Failure with ApiKey cmd run after certain time period


I am using katalon studio 7+ version on command line using apiKey
This works fine for certain time period (30 days approx) then it stops working

I tried it again by creating new apiKey which seems to be doing trick to work it again
However, documentation does not say anything about key expiry nor it gives option to set time period for it

Does any one know whether katalon studio 7+ apiKey has some default expiry time or how to make non-expiring

Any help on this is much appreciated !
