I use camunda Self-Managed. All User Task interfaces are 404.

Hi @Kric,

The below link might be of help to you

Migrate to Zeebe user tasks | Camunda 8 Docs

For job worker-based tasks only Tasklist API can do assignments.
Zeebe Task API can be used with zeebe user tasks.

Thank you very much, I found the official docs today when migrating camunda and remembered to come to the forum to reply, only to find that you replied a long time ago, I’ll have to check my email for notifications, thanks again .
