Nord pool get today and tomorrow lowest price get fetch consolidation error

Configuration
,
1

I consolidated the nordpool integration and making a sensor with both today and tomorrow and ran into a failure in the morning when tomorrow data was not available.

The consolidated template is based on this one which seems to have some error management: Nord Pool - Home Assistant

In the evening all was good - come morning on a restart - problem

all the sensors were unavailable I would expect the error management that I thought was in the original template to help take care of this but it seems on the error on tomorrow (values are not available yet) it just stopped everything.

I could use some help to understand this and maybe find a better way to deal with it than the work around I have come implemented

consolidated example code not working as is - works if use workaround in tomorrow get fetching todays date until after 13:00

            {{ results_consolidated }}

In debugging I checked the template example and that also fails - it does not output state: unavailable data: [] either - I think it did at some point, didn’t it? or maybe I misunderstand it? - could it be nord pool is sending a different message so the error handling is no longer working?

The workaround I have so far is to get this working is to change the tomorrow get to take today until 13:00:
{{ (now().date() + timedelta(days=1)) if (now().time().strftime('%H') | float ) >13 else now().date() }}

Anyone know

  1. how to deal with a failure in an action in a better way (to allow the script to keep running and deal with it later)
  2. should the official template take care of this failure and output state: unavailable data: [] ? if so maybe answering question 1. will be the solution?

if nothing else, here is a template for nordpool to consolidate today and tomorrow if you use the workaround currently commented out and change to your configuration id for nordpool

edit 250331 - fix in tomorrow today to ensure it includes on last day today and 1st day next month tomorrow
