Home Assistant 0.92.x: Uncaught TypeError: Cannot convert undefined or null to object about lovelace-slider-entity-row

[thomasloven]

Could you try opening slider-entity-row.js in any editor and just saving it again without any changes?

[thecode]

Done, still get the same error, I also noticed the error appears for all sliders (covers also, not only light)

2019-04-29 23:18:52 ERROR (MainThread) https://####.###/frontend_es5/app.0d431883.js:2:79851 Uncaught TypeError: Cannot convert undefined or null to object

[thecode]

I looked at the error more closlely with Chrome DevTools:

Uncaught TypeError: Cannot convert undefined or null to object at Function.keys (<anonymous>) at HTMLElement._listenKeyEventListeners (app.0d431883.js:2) at HTMLElement.attached (app.0d431883.js:2) at HTMLElement.value (app.0d431883.js:2)

Maybe this can help

I'm having the same error, on a new install of 0.92.1. Please let me know if there's anything I can do to help unravel the mystery.

Please let me know if this is still a problem with version v0.1

[thecode]

Still get the same error on two setups, I'm going to try only this module on fresh install to try to understand what is causing the error.

Could you please make sure the light is turned on and then go go /dev-state, find the entity in the list and copy the contents of the rightmost column for it and paste here?

I get the same error both for lights and covers.

[thecode]

I performed a clean Home Assistant Installation (v0.94.4).
Added only a cover component, checked it for a day without any errors.
After adding the slider-entity-row, error started to appear in logs.

Here is the complete lovelace test config:

    title: Home

Thank you for the effort, if there is something more I can do to test let me know.
