post-receive hook not running in Bitbucket 8.2.0

[Deleted user]

Using Bitbucket 8.2.0 server as a docker container on Linux (self-hosted), I'm having issues with post-receive hooks not running. The script is in the hooks/post-receive.d/ directory, and can be executed from the command line but is not run after a push, and there is no error message on the command line or in any log file. Even a simple hook message as suggested in the documentation https://confluence.atlassian.com/bitbucketserverkb/how-to-create-a-simple-hook-in-bitbucket-server-779171711.html is not run.

Are customer hook scripts still supported in 8.x? The 7.21 release notes stated that customer hook scripts would be deprecated in preparation for Bitbucket 8.0 ( https://confluence.atlassian.com/bitbucketserver/bitbucket-data-center-and-server-7-21-release-notes-1115129015.html )
