ActionView cache handling has been changed in Rails 6.0.0.rc1.

It takes us hours to find that versioncake was the reason of the following vague errors:

We too have been chasing the elusive compute_if_absent issue and suspected this gem. If we come up with an elegant solution, I'll share it. Thanks.
FYI this hack satisfied my needs https://github.com/trak3r/versioncake/pull/1/files
I realize it's not a patch worthy of the master branch but might help others who arrive here looking for help.
Sorry for the trouble and thanks for the referenced files
