Trying to use the provided scripts to generate docker images for Workbench and running into this issue:
Step 12/13 : RUN /tmp/buildpack/php/bin/compile /app /tmp/build_cache /tmp/env ---> Running in 177d23e5a188
ERROR: Failed to download standard library for bootstrapping This is most likely a temporary internal error. If the problem persists, make sure that you are not running a custom or forked version of the Heroku PHP buildpack which may need updating.
Everything up until this point has worked, but it fails on that. I tried changing the buildpack to a different version, that didn't help.
