I'm updating an old Play project and upgrading to the latest version of Play, but am having some problems with swagger.
I get this error, which I don't know how to resolve:

Does anyone know what might help, or where the error might lie?
The main blocker is that Play 2.8.8 is compatible with Jackson 2.11.x, not 2.12.x. You'll have to make sure to use only Jackson 2.11.x.
I'd recommend that you run sbt dependencyBrowseTree to have a view of the dependency tree and make sure only Jackson version is used across all the dependencies. You can define some overrideDependencies as well to help consistency.
It's also likely that you will need to:
