Hello,
This should now be fixed, sorry to ear that you have been impacted by this.
This is due to an automated update of the buildpacks we are using ( heroku ), the new version of nodejs-function require a CNB API version higher that the one we were previously using (0.9 instead of 0.8). Due to this error, the buildpacks were not able to launch during a few hours.
We have now updated the version we use to the 0.9, this issue should be fixed.
From now, we will make sure to check for non-regression before promoting the buildpacks.
Sorry again,
Bastien
