Buildpack 'bin/release' script errors are no longer ignored
Change effective on 15 June 2022
Previously if these
bin/release scripts exited with a non-zero exit code, the Heroku build system would
ignore the failure and continue with the rest of the build.
Now, the build will be marked as a failure and any output from the failing
bin/release script included
in the build log.
If you encounter such errors (“
The buildpack's bin/release script did not complete successfully”),
ensure you are using the latest version of the failing buildpack, and then report the issue to the
maintainer of that buildpack.
