Error while using setContents

[dgandhi1993]

Hi @JiHong88

I am facing this issue for quite some time now, however, I am not able to figure out the root cause.

When I try to set my editor's content using setContents(), I get below error:

Uncaught TypeError: Cannot read property 'scrollTop' of null
    at Object.getOffset (util.js:1021)
    at Object.setControllerPosition (core.js:755)
    at Object.call_controller (math.js:244)
    at Object.active (math.js:215)
    at Object._applyTagEffects (core.js:5305)
    at Object._onChange_historyStack (core.js:5011)
    at h (history.js:86)
    at Object.push (history.js:109)
    at Object.setContents (core.js:4411)
    at Object.setContents (core.js:7448)

The same code usually works fine, but at times gives the above error.
Once this code breaks, my entire business logic in its parent function stops.

Can you help rectify this edge case?

@dgandhi1993 When is "setContents" called?
And show me the contents of "setContents".

[dgandhi1993]

setContents is called with an empty string long after the editor instance initialization.

Basically, I am trying to clear the editor's content.

@dgandhi1993 If you are trying to set the initial values of the editor, you should do it in one of three ways:

1. call setContents inside onload
   instance.onload = (core) => core.setContents("");

2. value option
   suneditor.create("id", {value: ""})

3. just empty textarea

@JiHong88 I am using the value property. This issue appears when I am trying to change an existing editor instance value.
Also, this doesn't happen always.
