can't make regex to work

[medyagh]

I try

travisBuddy:
    regex: '(\d+ Error)'
    regexOptions: "g"

and I still get the full log: https://github.com/kubernetes/minikube/pull/5530#issuecomment-538564946

I had tried with double quotes but it makes the yaml to error for escape problems, and would cause the travis job not run at all.

any tips that I could make travis-buddy only return matching lines ?
