Thanks @levmyshkin, the steps you provided in #5 🐛 EPT Columns/container won't load Closed: cannot reproduce helped me with this same issue. While I am not using Mercury, switching to using the Layout paragraphs widget and setting the depth to at least 4 helped with the EPT Columns not displaying when selected. 👍🏽
I had this same issue and the patch in #12 worked for me.
This has been reviewed and merged into the latest dev commit
I got this same error as well. Had to rollback the update to 2.0.0-alpha3 for now.
Out of curiosity was the Section that used the tabs in layout builder removed first? I had this issue as well but I figured it was because I forgot to remove the Section that used the tabs before I uninstalled the module.
I had this issue as well and the patch in #17 worked for me.
It might be a silly question but based on what I read from your article, for someone who has created a Drupal 7 module following the convention 7.x-X.Y and now trying to upgrade that module for Drupal 10, is the recommendation using semver to just use 1.0.0 or 2.0.0 instead of 10.x-X.Y?
Confirming that I stumbled across this issue as well. Patch in #3 fixes this issue.
Confirming the patch in #3 worked for me as well.
I believe "confirms" should really be "conforms" in the first paragraph.
