Input Select - Set Options using templates

I am having a problem with the input_select.set_option service.

I have a number of announcements that my system can call upon and I want to have an input_select populated at HA Start with those announcement names.

I create a list of announcements to use in the input_select.set_options like this:

      - service: input_select.set_options
        data_template:
          entity_id: >
            input_select.announcements
          options: >
            {% for script in states.script if 'script.announcement_' in script.entity_id %}
              {%- if loop.first %}
                {{ '["- Select Announcement -", '}}
              {%- endif %}
              {%- set entity = script.entity_id | replace('script.announcement_', '') %}
              {%- set entity = entity | replace('_', ' ') | title -%}
              "{{- entity -}}
              {% if not loop.last -%}
                {{ '", ' }}
              {%- else -%}
                {{ '"]' }}
              {% endif %}
            {%- endfor %} 

Which to save you working it out creates something in this format:

["- Select Announcement -", "Announcement name 1", "Announcement name 2", ... "Announcement name n"]

This fails because the resultant string is more than 255 characters. (The second last line of the error output looks a bit odd to me… f"Invalid state )

    f"Invalid state encountered for entity id: {entity_id}. "

However,

If I use the exact same template as above in the Dev Template Tool to create the same string and use it in the Dev Tools Services it works fine. So the 255 limit seems to be selective!

As an illustration of it working with a string longer than 255 chars:

I have also tried publishing it to MQTT and using the trigger.payload but that doesn’t work either.

On the one hand I can’t believe no one has tried this before so it must be possible and I must be doing something wrong, but on the other hand I think I have found a bug somewhere…

Any ideas?
