Hello,
I have a github repo (https://github.com/reconhub/incidence) that uses travis to check cromulence with R and upload coverage statistics to codecov.io (https://codecov.io/gh/reconhub/incidence).
Sometime in the last month, an env variable that we use to trigger the build env to send the tests to codecov started thowing a “Bad substitution” error: https://travis-ci.org/reconhub/incidence/jobs/477198052#L1242
Can anyone help shed light on why this is happening?
