Holoviews Renders Throwing error

HoloViews
1

I am creating a HoloMap and the converting it to Bokeh implementation (which I used further) I’m doing the following:

renderer = hv.renderer(‘bokeh’)
plot = renderer.get_plot(holomap).state

Initially, this was working but Now I’m getting the following error

failed to validate Figure(id='1046', ...).align: expected an element of either Enum('start', 'center', 'end') or Tuple(Enum('start', 'center', 'end'), Enum('start', 'center', 'end')), got None

I double-checked the versions (1.13.2) so that if this is related to the version issue, also verified the data but still couldn’t find any changes.

Can you please help here?

In Holoview opts I added:

align=‘centre’

Now I’m getting:

holoviews.core.options.AbbreviatedException: AttributeError: ‘str’ object has no attribute ‘dataspecs’
