HA was running fine - latest version, under HAOS on an x86. Ran a few updates and installed the Toyota and waste collection integrations, all seemed good, but when I looked at the overview, I got the message:
Error loading the dashboard strategy:
TypeError: Failed to fetch dynamically imported module: http://homeassistant.local:8123/frontend_latest/18518.17b4d47b9637b95d.js
Totally lost as to where to start looking
Start by uninstalling the new integrations one by one and observing whether the error goes away. Hopefully that isolates the problem to one specific integration.
Do you know whether the error showed up only after the integrations were installed? If not, what updates did you run?
All very curious. I removed the 2 integrations (Toyota and Waste collection) I had added and the fault persisted. I wasn’t able to reverse the updates (to ESPhome device builder, Advanced SSH & web terminal, Samba and HA core) so I restored from the backup the the system took this morning.
After refreshing the browser, the fault cleared, so I re-applied the updates, then deleted Moonraker (as I no longer use it), and added the Waste Collection and Toyota EU integrations. All the same as last time, but now all works well.
The only thing that seemed different is that on the first attempt, one of the updates seemed to take very little time to complete, and on the second attempt it took much longer, so I wonder if on the first attempt the download was incomplete? Sadly, I can’t remember which update it was that was so quick…
Thanks for your help, and thanks to whoever wrote the automatic backup system.
