Not sure what the ArgumentError: Unrecognized ActiveSupport::Cache.format_version: 8.0 means. Dropping the following line removes the error:

globalid/test/cases/railtie_test.rb

Line 19 in e9548a3

@app.config.active_support.cache_format_version = Rails::VERSION::STRING.to_f

But it was introduced for some purpose:

Checking the source code / documentation, it should likely be always 7.0 for the moment, unless there is some smarter way to detect the supported formats, because ideally, it should be the most recent supported.
