For anyone who ran into this issue when baking lightmap for dynamically created mesh. Make an editor tool and write:
EditorPrefs.SetBool("MeshRendererEditor.Lighting.ShowSettings", false);
This closes the *Lighting* part in the Inspector of the MeshRenderer. I just notified that the error disappeared after I close the *Lighting* part.

Hi folks, I just came across this. For me, I had to clear all the flags from each mesh renderer in the prefab and then clear the occlusion culling. That cleared up the errors in the console. Hope it helps.
