Since you did not specify what language you are using, you can use lookbehind.

DEMO

(?<=error: )(.*)

This looks for lines starting with "error:", and matches everything that follows afterwards. This will match a single line though.

If your messages always start with error: you might as well just use substring. You didn't say which language you were using, but this would do the trick in javascript :

message.substring(7)
