Starting today all build even after clearing cache are failing WITHOUT any errors - locally builds fine.
I have 3 other clients that are having build fails. Then after the build says it fails it passes.
This one client just fails and even in the notification hook into slack it sends out 5 failed messages instead of one like it has for the past year.
