[5.x]: Craft 5 upgrade error: A field layout element is missing its UUID

What happened?

Description

Hi @brandonkelly - I'm getting a very similar error to https://github.com/craftcms/cms/issues/16032 when upgrading to Craft 5.

I am upgrading from Craft 4.13.9 to 5.5.9.

The error I'm getting is:

Exception: A field layout element is missing its UUID. Reinstall Craft CMS ^4.4.14 and run `utils/fix-field-layout-uids` before upgrading to Craft CMS 5.

I only get this error when deploying the upgrade to the staging server. The upgrade works fine on local.

I rolled back to Craft 4 and ran utils/fix-field-layout-uids but it output that there was nothing to fix. I continued on with the Craft 5 upgrade for a second try and got the same error.

Expected behavior

Migrations to run and upgrade to craft 5.

Actual behavior

Migration fails with above error

Craft CMS version

Upgrading 4.13.9 to 5.5.9

PHP version

8.3.14

Operating system and version

Linux 6.8.0-44-generic

Database type and version

MySQL 8.0.40

Image driver and version

Imagick 3.7.0 (ImageMagick 6.9.12-98)

Installed plugins and versions

• Amazon S3 2.2.1
• Bugsnag 5.0.0
• CKEditor 4.4.0
• Freeform 5.8.6
• Super Table 4.0.2

Start by comparing the local and staging upgrade environments, then review the Craft 4 utils/fix-field-layout-uids output and the Craft 5 migration that reports the missing UUID. Done means identifying why staging still contains an invalid field layout and confirming that the Craft 4 to 5 migration completes successfully there.
