JSON API returns error for "/json/live"

[Cerothen]

What happened?

When attempting to use the http://host/liveview page nothing was loading, upon closer inspection the api located at http://host/json/live was returning the following:

{"error": 4}

The "Peek" feature in the regular UI works as expected however it is communicating using websocket messages and not with the same JSON api resource

To Reproduce Bug

Navigate to http://host/liveview when using version 0.15.0-b6 "Kosen"

Expected Behavior

The assumption is that the http://host/json/live api resource would return a non-error

Install Method

Binary from WLED.me

What version of WLED?

WLED 0.15.0-b6 (build 2410140)

Which microcontroller/board are you seeing the problem on?

ESP8266

Relevant log/trace output

No response

Anything else?

JSON live has been disabled by default in b6.

[Cerothen]

Is the intent to have the live view page be removed or switch to use the websocket?

[blazoncek]

If you want to use it, custom compile. Otherwise switch to websockects as it is more efficient.

[netmindz]

Could we have a check during the build that catches these incompatible set of build options?

[blazoncek]

If the JSON live is needed (please get users to upvote this issue) then it can be enabled in release builds.
It was omitted in an attempt to reduce binary size to fit other more important features in the future.

I'm not directly aware of what's needed to address the websocket however the liveview page depends on the JSON/live API. I'm just wondering if the liveview page will be rewritten to use websockets or if it is going to be removed

[blazoncek]

Web UI (including /liveview) uses websockets.
Nothing special needed.
