Anyone here had already encounter this error before ? I am trying to upgrade my site from v8 to v13. Right now I tried running from v8 to v9 so far it went well when im trying to upgrade to v10 it gets me this error. https://cdn.discordapp.com/attachments/1255010619174682624/1255010619527008256/image.png?ex=667b9338&is=667a41b8&hm=90eeca7618d2d2a097ff8d4b1e2ca4af8f968aa9f4d7a725883b1878b46d1d18&

maybe an issue with wrong version of forms installed? and did you clean the dll's first?

when I'm on v9 I installed the latest version of form and the same with v10 . yeah I did clean the project.

https://discord.com/channels/869656431308189746/1201864111877795907 has a link to the official guide. The Forms error looks like Forms isn't correctly installed into your v10 upgrade - or that Umbraco startup (

startup/Program

etc) hasn't been updated to match Forms v10. Can you make sure Forms is installed correctly? If you create a blank v10 and install Forms, you should have a minimal reference.

Is this error not related to any DB connection?

That looks unlikely. It looks like a part of Forms is not installed (package-referenced) or registered (in startup/program). What makes you think it's databased?

I'm thinking of since I have migrated all the forms from the files to store in database. Maybe that's one of the reason ? but ill try recreate things and make empty project for v10
