Thanks for the Pr.

[jtuchscherer]

It is probably worth noting that this requires the RLP gateway to be deployed, which has been included in cf-deployment 4.5 (https://github.com/cloudfoundry/cf-deployment/releases/tag/v4.5.0)

[jtuchscherer]

@shinji62 Do you need something else to be able to pull in this PR? We would be happy to help.

[shinji62]

@jtuchscherer No it's fine. I would try to merge this week.

Sorry for the delay I am a bit busy now.

[jtuchscherer]

No rush. Let us know if you need any help or support.

I guess some vendored dependency are missing.

@shinji62 I created this bug to have the team look into this: https://www.pivotaltracker.com/story/show/164885375

@shinji62

I tried a fresh clone of our work and didn't get the error you're seeing, but I did get some strange type errors. I ran GO111MODULE=on go test ./... and it worked--possibly not the answer you're looking for, but could we have more information about how you're running this?

@shinji62 @jtuchscherer @MasslessParticle
It was indeed missing dependencies. We added them and opened a new PR:

#214

Any idea when i release will be cut with this change?
