Dreamer implementation no longer seems to work with Ray 1.2

Hi all! I recently updated my Ray to version 1.2, and I’ve discovered that the Dreamer code no longer functions. In particular, any time I attempt to initialize the Dreamer trainer I’m met with the same errors as listed on this GitHub issue: [rllib] AttributeError: ‘list’ object has no attribute ‘float’, when using dreamer · Issue #14107 · ray-project/ray · GitHub

Would anyone have any insight as to what about the Ray 1.2 update may have caused this issue, and how I might be able to fix it?
