Pdf prinf live component

when trying to manually render a liveview for subsequent pdf print I get
an error when a live component is in the liveview render template

using this

assigns_map
|> LiveViewModule.render()
|> Phoenix.HTML.Safe.to_iodata()
|> to_string()

with assign_map containing all necessary assigns for the live view

with a liveview with render function containing another live component like

~H"“”
<.other_live_component …>
“”"
the error message is

** (ArgumentError) cannot convert component OtheLiveComponent with id 116158 to HTML.

A component must always be returned directly as part of a LiveView template.
For example, this is not allowed:

<%= content_tag :div do %>
  <.live_component module={SomeComponent} id="myid" />
<% end %>

That’s because the component is inside content_tag. However, this works:

<div>
  <.live_component module={SomeComponent} id="myid" />
</div>

Components are also allowed inside Elixir’s special forms, such as
if, for, case, and friends.

<%= for item <- items do %>
  <.live_component module={SomeComponent} id={item} />
<% end %>

However, using other module functions such as Enum, will not work:

<%= Enum.map(items, fn item -> %>
  <.live_component module={SomeComponent} id={item} />
<% end %>

Now if I call directly Other_live_component, it works ok.
I’m not in any of the cases excluded by error message explanation

Where Next?
