@iancward thank you for your contribution - due to organization policy, we unfortunately we cannot accept any PRs without the CLA signed (see here for instructions on how to do this).

If this is still something you're interested in fixing this, please re-open a new PR once you have signed the CLA - thanks!

Hi @pichlermarc, apologies, the EasyCLA process is new for my company and it's taking significantly longer than expected to find the right folks to handle the paperwork, even though our legal team has signed off on the CCLA.

I'll open a new PR once this is is taken care of. Thanks!
