Incompatible with 2022.7?

[IDmedia]

Tried upgrading HA to 2022.7 and I'm getting "Unknown error" without any errors in the console or logs.
Can't get the UI to show until I comment out my lovelace_gen include. Anyone else having this issue?

Example from my UI-lovelace.yaml file causing the error:

      - !include
        - lovelace/xiaomi_vacuum.yaml
        - vacuum: vacuum.rockrobo_2nd_floor
          camera: camera.rockrobo_2nd_floor_map
          zones: input_select.rockrobo_2nd_floor_zones
          title: Second Floor Vacuum

I'm having the issue and commenting out some of my includes makes it work, but i cannot for the life of me see why those are causing it to fail. Doesn't seem to be anything in the breaking changes of 2022.7 that would apply to me.

The only thing I can see is that Home Assistant changed to Python 3.10 and that the jinja2 package has been updated and the integration doesn't pin the version: https://github.com/pallets/jinja/releases

Can't yet see why it should break though.

I think it has to do with "Our YAML & JSON tooling improved, using faster libraries and methods".

Other than with lovelace_gen I also had some issues with emoji's in template strings.

But it's a strange issue: my YAML files using lovelace_gen are working fine when included in my "desktop" dashboard, yet the exact same files are throwing an error when included in my "phone" dashboard.

Bit more digging, i found this in my log file.

File "/usr/local/lib/python3.10/site-packages/jinja2/loaders.py", line 195, in get_source
    pieces = split_template_path(template)
  File "/usr/local/lib/python3.10/site-packages/jinja2/loaders.py", line 36, in split_template_path
    raise TemplateNotFound(template)
jinja2.exceptions.TemplateNotFound: /config/lovelace/dashboards/../views/office.yaml

Path is correct, if i remove # lovelace_gen and change to a standard card include in that file (ie no jinja2) it picks up the file in that location.

edit

Some more oddities.

icon: mdi:home-assistant
title: Room
cards:
  - !include
    - ../cards/heating.yaml
    - entity: office

This works with multi level attributes but no # lovelace_gen at the top of the file. Something very weird is going on. add # lovelace_gen at the top and it breaks.

So dug into the changes in the core yaml loader which this imports and it seems references to SafeLineLoader have been replaced with LoaderType

I've not tested yet, but I'm guessing these two lines.

loader.SafeLineLoader.add_constructor("!include", _include_yaml)
loader.SafeLineLoader.add_constructor("!file", _uncache_file)

Need to change.

[chriscolden]

So just pored over the jinja2 loader.py file and found that split_template_path will throw a template not found if the path has a .. in it. I was doing this to keep cards, dashboards and views seperate. Soon as moved them all into the same directory its started working. Not saying the lovelace_gen doesn't need some work to follow the improvements made in the latest release as it does look like it does to me, but will leave that up to @thomasloven

@chriscolden Does it mean it then works for you on the latest version of HA? I'm still struggling to get it to work at all after upgrading

[chriscolden]

yeah im working again it would seem.
i had a directory structure of
config/lovelace/cards
config/lovelace/dashboards
config/lovelace/views

which means i had to ../ out the directory to get to my next inlcude.

Just moved to
config/lovelace/dashboards
config/lovelace/dashboards/views
config/lovelace/dashboards/views/cards

then replaced ../ with ./

and it seems to have sprung into life.

[chriscolden]

@IDmedia do you see this in your logs when you load a dashboard?

jinja2.exceptions.TemplateNotFound: /config/lovelace/dashboards/../views/office.yaml

[IDmedia]

No, I'm not using '..' in the path. No visible errors in the logs or console except the "unknown error" message when trying to view the dashboard.

[chriscolden]

you will have to post some examples. maybe create a new dashboard for testing, or at least comment out most of it and post whats not working for you.

The example is in the initial post (same goes for the path). Once I comment the lovelace_gen yaml out everything works so I know it's causing the issue. Something changed in the latest version of HA, just not sure what yet.

[chriscolden]

So what's in the lovelace/xiaomi_vacuum.yaml file? just standard yaml?

[chriscolden]

Did you see this about that file.

Important: For some reason, which I can't seem to nail down, things stop working if you add # lovelace_gen to ui-lovelace.yaml. Adding it to any file included from ui-lovelace.yaml works, though.

[chriscolden]

I'm not using lovelace_gen in that file. mines still on storage mode, and i include a separate dashboards which use lovelace_gen. thats the only think i can glean here.
