I’m new to the community and apologize if this is not the correct place to post this but I’ve been fighting this for a week or two now without any luck. I have disabled all my integrations and even did a restore to try to figure out what is causing this issues but nothing seems to be working. When going to the Overview dashboard or any new dashboard created I get the following error
TypeError: undefined is not an object (evaluating ‘t.toUpperCase’)
Anyone have any suggestions on how to figure out what card/entity might be causing this error?
Which version of HA are you running?
Thanks for responding I’m running HA on a raspberry pi and below is the version information I’m running.
Home Assistant Core 2022.5.3
Home Assistant Supervisor 2022.05.1
Home Assistant OS 7.6
Kernel version 5.10.103-v8
Agent version 1.2.1
Try clearing your browser cache.
I have tried that I actually do that after every restart of HA. I have tested from multiple browsers/devices and the problem still exists the only difference is the error changes slightly when using some of the other browsers. The error above is from Safari and below is the error from Chrome and Edge the difference is the t exists in safari but not in the others
TypeError: Cannot read properties of undefined (reading ‘toUpperCase’)
not sure how to find the problem i see this message though
