After updating to versions bokeh==2.4.0 and holoviews==1.14.6, running
import holoviews as hv
hv.extension("bokeh")
plot = hv.HLine(0.5).opts(tools=["hover"])

ValueError: failed to validate HoverTool(id='1420', ...).renderers: expected an element of either Auto or List(Instance(DataRenderer)), got [None]
Previously, with bokeh==2.3.3 and holoviews==1.14.4 a plot was produced but no information was displayed when hovering over the line:
