Error in checking git rev-parse HEAD

[frensjan]

When executing

spark-package publish -c ".sp-creds.txt" -n "TargetHolding/pyspark-cassandra" -v 0.3.4 -f . -z target/pyspark-cassandra-0.3.4.zip

i get the following error

ERROR: Error while accessing commit on Github. Are you sure that you pushed your local commit to the remote repository?

While

$ git rev-parse HEAD
e3b880d00f80d1d4dd43691be06c12e9fad1d79d

matches [https://github.com/TargetHolding/pyspark-cassandra/commit/e3b880d00f80d1d4dd43691be06c12e9fad1d79d].
And git also claims I'm up to date:

$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean

or with git push

$ git push
Everything up-to-date

Any suggestions?
