[Drupal 10, Drush 11] PHP Fatal error on install

Tested and working.

Adding a fixed patch to avoid unexpected changes. This works for us too.

https://git.drupalcode.org/project/csv_serialization/-/merge_requests/12 in the newer issue https://www.drupal.org/project/csv_serialization/issues/3327819 🐛 csv_serialization not compatible with Symfony D10 Closed: duplicate is more complete than https://git.drupalcode.org/project/csv_serialization/-/merge_requests/10 on this issue, because it also fixes decode.

Either we mark this one as duplicate and go on the other one, or we mark the other one as duplicate and we update the MR here.

Marking this as a duplicate of 🐛 csv_serialization not compatible with Symfony D10 Closed: duplicate because, as mentioned by @GuillaumeDuveau, that issue also has a fix for decode.

I'm confused, both issues were marked as duplicate, this one and the referenced. Which one should we go with?!

@alfattal 🐛 csv_serialization not compatible with Symfony D10 Closed: duplicate was marked as a duplicate of #3280951-15: Drupal 10 compatibility → , so it's already fixed. Just use the 3.0.0 release, it's in there.

@fenstrat Thank you for the clarification. Yes, I tried the 3.0.0 version, and it is giving me the same error message. I'm on Drupal core version 9.5.8. Is the 3.0.0 version work only with Drupal 10?

@alfattal Yes, 3.0.0 works only with Drupal 10. See 📌 Release that is compatible with D9 and D10 Closed: works as designed for a more detailed explanation.

By the way https://www.drupal.org/project/upgrade_status → seems to think that 3.0.0 is D9 / 10 compatible so advises my D9 site to upgrade to 3.0.0 - which causes my D9 site to go down. Correct advice should be to uninstall csv_serialization

Correct advice should be to uninstall csv_serialization

csv_serialization can be updated at the same time that you update Drupal core to D10.

csv_serialization can be updated at the same time that you update Drupal core to D10.

OK but I just meant for people using https://www.drupal.org/project/upgrade_status → - the advice given for any module on /admin/reports/upgrade-status boils down to yes there is a D9 / D10 version available so Update, or there is no D9 / D10 version available so uninstall / Remove the module. So I guess csv_serialization 3.0.0 (D10 only) is a middle category which https://www.drupal.org/project/upgrade_status → does not cover.

/admin/reports/upgrade-status currently advises D9 sites to Update csv_serialization to 3.0.0, I am not sure where https://www.drupal.org/project/upgrade_status → reads its information from

Yep. Had the same issue. Had to downgrade to 2.x-dev for our d10 prep story, then switch to 3.0 when we did the actual d10 upgrade.
