[SOLVED] - HASS Core - Logbook,History, Services, Template and Events "Error while loading page"

Running HomeAssistant core 0.114.4 and Logbook,History, Services, Template and Events all give the error "Error while loading page ". These all worked on 0.113.3. This is the error in the log when each of the problematic page is selected:

2020-08-27 08:41:00 ERROR (MainThread) [frontend.js.latest.202007160] https://hass.domain.com:8123/frontend_latest/chunk.cf565e41b8a8dce0642a.js:133:204 TypeError: this.shadowRoot.querySelector(...) is null

That’s a frontend (Lovelace) error. It has nothing to do with the integrations that you mentioned can’t be set up.

@tom_l Any suggestion to dig into this further? I only get the error when those items are selected.

The errors related to the integrations would help.

There were no integration errors.

Seems the issue was cause by connecting via an old link prior to upgrading to 0.114.4. Simply going back to the overview and refreshing the page fixed it.
