Losing field content after migration

[georgiaevans]

Describe the bug

I am in the process of upgrading a project to craft 5. The migrations run smoothly, but I lose all content in hyper fields after running a craft up.

I have tried resaving the entries before running migrations but all content is still being lost after migrations.

Have you had this issue? Do you have any suggestions of how to fix this?

Steps to reproduce

1. Upgrade project
2. Run craft up

Craft CMS version

5.8.10

Plugin version

2.2.7

Multi-site?

No

This'll be a first I've heard of this! Can you comment on what version of Craft/Hyper you were on before doing the upgrade?

Can you also hop into the database of an entry that you know should contain Hyper content, and verify if there's actual data in there, or empty? For example, here's what an entries content might look like:

{
	"bbd727b1-638c-452d-9041-26edea43bc32": [
		{
			"type": "verbb\\hyper\\links\\Entry",
			"handle": "default-verbb-hyper-links-entry",
			"linkValue": [
				2192
			],
			"newWindow": false,
			"linkSiteId": 3
		}
	]
}
