Release with the issue:
HA: 2021.12.1
frigate-hass-card: v2.1.0
AlexxIT/WebRTC card: v2.2.0

Last working release (if known):
Not known

Browser and Operating System:
Android companion app - beta-1776-8c5149dd-full (issue is also happening on latest Play Store version)

Description of problem:

Occasionally when I open the HA companion app I get the below error, this issue doesn't occur when I use the regular WebRTC camera card on it's own (https://github.com/AlexxIT/WebRTC). Please note it's only an occasional error and only happens sporadically (approx 1 or 2 times out of 10).
The card loads fine if I close the app and open it again, or tap the clips/recordings button and then go back to live view.

Javascript errors shown in the web inspector (if applicable):

N/A

Additional information:

Thanks for the report @conorlap ! I have not seen this before. Perhaps some sort of race condition between the Frigate card loading and the resources for the rest of the page loading. If the Frigate card loaded before WebRTC, it wouldn't be able to find the webrtc-camera element and you'd probably get that error.

I've been also getting this error since upgrading to the following, I've also uninstalled and reinstalled the card. Dermotduffy did you solve?

HA: 2021.12.1
frigate-hass-card: v2.1.0
AlexxIT/WebRTC card: v2.2.0

@cappiel didn't even get a chance to investigate yet ;-)

When you say "since upgrading", do you mean it used to not be a problem -- then you upgraded the card -- then it was a problem? Is this the Frigate card, of the WebRTC card? Do you know what version(s) you were on before?

[cappiel]

@dermotduffy all good! sorry that came across bad haha

Yea, so I upgraded HA to 2021.12.1 on Sunday. That broke WebRTC I know. AlexxIT fixed that with 2.2. and installed that earlier today.

I'm pretty sure I upgraded your card on Sunday also to 2.1 through HACS. Seeing similar issue as Conor above. (Not Android though, web and/or iOS HA app)

Any logs I can pull for ya?

[dermotduffy]

Thanks @cappiel , no worries! So sounds like you did a big upgrade of HA, WebRTC and the Frigate card -- so can't really pin it down :-(

@conorlap was this triggered by a recent upgrade for you also, or "always" been this way?

[conorlap]

@dermotduffy I've only setup Frigate and this card within the past week so not sure how long this issue has been present.

With a caution that I could never reproduce this bug on any device (and so cannot test it has fixed the issue), I think the merged PR fixes at least one race condition I could imagine during loading that may cause the described behavior. If someone has this issue reliably, would love your feedback after the next release to determine if it's really fixed correctly.
