undefined method `to_ary` for Enumerator (Rails 7.1.1 & Activeadmin 3.1.0) about activeadmin

[gsar]

this is a regression in rails 7.1.0. i see there is a PR that has been merged into the upcoming 7.1.2 release branch.

Thank you. Sorry, there isn't anything actionable here. This could depend on several factors. We use Rails 7.1.1 as part of the default dev workflow here and I'm able to export a CSV on any index page using the development app just fine. No reports on my side with our own ActiveAdmin usage either as we run v3.1.0. I'd suggest creating a reproduction to isolate the issue as that would be most helpful for identifying and fixing this. We would be open to a PR to resolve it as well. Thanks.

Hi @javierjulio I did some more debugging and it looks like it's due to the Activeadmin CSV streaming option.

If you're testing on development trying adding config.disable_streaming_in = %w[staging] to your config/initializers/active_admin.rb. This will enable the CSV streaming for development and you will get the previously menntioned error.

Right now, the temporary solution to get around this issue is disabling CSV streaming but it's not an ideal permanent solution.

Please consider re-opening this issue, thank you.

Thank you, I also see another PR for the same issue. Thank you all, I guess we'll just have to wait for a Rails 7.1.2 release to fix this issue.
