ERROR (MainThread) [frontend.js.latest.201902200] :0:0 Script error


I am seeing this error in my log, being raised around 4 times a second (so filling up my log quickly!) after upgrading from 0.88 to 0.95

ERROR (MainThread) [frontend.js.latest.201902200] :0:0 Script error.

I am running installed on MacOS, so perfromed the upgrade using pip3 install --upgrade homeassistant as per the documentation.

Can someone point me in the next direction to troubleshoot please?

Managed to resolve this. Had an iOS device displaying a custom page in the HA iOS app. Closed the app on the iOS device, cleared Safari cache and history and then re-opened again.

Errors stopped after that
