Hi,
I made a small change to the node-red-blink1, to update the underlying node-blink1 library version (which works with modern NodeJs).
However, on submitting the pull-request, I'm noticing a lot of Travis CI errors on seemingly unrelated issues (exif node [...] Fatal error: expected Array [). Is this a known issue with the CI setup? Or did I do something dumb? https://travis-ci.org/github/node-red/node-red-nodes/jobs/754417045
