So I just did a quick check of running dovecot with a standalone
solr-8.7.0 instance and I'm not seeing any issues.

I confirm I haven't configured anything for indexer or indexer-worker in
dovecot, just left the defaults.

For 401's returned from your solr server you'll need to look into how
you set up authentication.
