Panel_iframes.yaml erased when HA restarts

I am running HA in a docker container, and I have a panel_iframes.yaml include in my configuration.yaml. My HA setup is configured to update automatically, and this morning when I went to restart everything (I was working on something else). When it came up, all of a sudden my panel_iframe.yaml was blank. Not that HA wasnt reading it. I open the file in Notepad++ and…blank file. I enter a few panels back intot he file (node-red, esphome…both running in docker on the same machine). Save the file. Reopen the file just to check…info still there. Restart HA and…panel-iframe.yaml blank again.

Does anyone have any idea wht restarting HA would delete contents of panel_iframe.yaml? Doesnt delete the file, it just erases all the content in the file.

It looks like all my input booleans (input-booleans.yaml) are gone as well, but I have a feeling its the same issue, so I am focusing on the panel-iframe.yaml at the moment.

ANyone have any ideas?

I have no clue how this is happening, but can you tell us which version you were updating from and which version to?

Are you running Supervisor or something else?

The more info you can give, the more likely someone can help.

I dont think I am running supervisor. I think I have the self-hosted version. In the version menu it says:
Home Assistant 2022.8.1
Frontend 20220802.0 - latest

When I check the logs, I see an error about nodered and some warnings about HACS integrations, but nothing about Panle_iframe at all. Here’s the nodered error if it helps:

2022-09-16 19:29:29.079 ERROR (MainThread) [homeassistant.helpers.integration_platform] Unexpected error importing nodered/diagnostics.py

Ho did you add the panel_iframe? …did you edit your config,.yaml directly (can you show that section)?
