Unknown error during build

Build 294325
I have done 3 builds and keep getting “unknown error please contact support for help”
When I get the email telling me the build has failed, it says to correct the errors and try again.

If it doesn’t tell me what the errors are how can I correct them?

Hi,

There is some bugs with the build service that we’re working on fixing at the moment, so there is probably nothing wrong with your build. It should be working soon so you can try again, sorry for the inconvenience!

Hi, are these bugs fixed?
I have the same issue with runtime 3.3.5
