On latest tag=2.0.3 with fresh clone and make clean, then make demo build and Drupal install got to the point after importing 'islandora_tags' then failed with a search_api_solr error:

FWIW, docker compose exec -T drupal with-contenv bash -lc 'composer require "drupal/search_api_solr:4.3.0 as 4.2" -W' worked to get Search API Solr working.
