Panic: runtime error: index out of range [0] with length 0 with drone 1.9.1 and Bitbucket server v6.10.5

Hi

I’m trying to get drone running with Bitbucket Server v6.10.5.

When using drone 1.10.1 I can’t activate reporsitories as reported here: https://github.com/drone/go-scm/issues/88

When using drone 1.9.1 creating a new build fails with the following panic in the drone server.

Panic: runtime error: index out of range [0] with length 0
