Unable to install contrib into my flogo setup (docker)

[meta-research-jack]

Hi there, I was trying to install "Pulsar subscriber" contrib with this URL: github.com/project-flogo/messaging-contrib/pulsar/trigger/subscriber
However getting the error log below:

Do you have any idea what could have been gone wrong?

I was using web UI to perform the installation.
