Cannot read property 'innerText' of null at Y (App.svelte:359)

[NawaNae]

at App.svelte:359

document.querySelector('[class^=textArea-] span').innerText; 

the return value of querySelector is null

my discordCanary dom of textArea does not contain any span
like

<textarea ... class="textArea-2CLwUE fontSize16Padding-XoMpjI scrollbarGhostHairline-2LpzZ9 scrollbar-3vVt8d"></textarea>

so I am not sure if just change this line into

document.querySelector('[class^=textArea-]').innerText; 

can solve this problem or not

(I don't know how to debug this plugin sorry)

Thanks a lot

Are you still encountering this issue? We have been unable to replicate this till date, even in Canary

---

so I am not sure if just change this line into:

document.querySelector('[class^=textArea-]').innerText; 

It should indeed suppress the error, and may even still work as expected, however I can't entirely be sure until encountering it on my end too

I still encountered this issue in my canary, and I find the difference between Canary, PTB and Discord.

Env

Canary 124017 (2c2001f)
BetterDiscord 1.5.3

The message sending box (textarea) are using different element to implement

Canary

PTB & Discord

So, canary only uses placeholder attr of textarea to show the message in message sending box (PTB and discord use div and span to show)

Experiment

I tried to insert a fake span in textarea using

var fakeSpan = document.createElement("span")
fakeSpan.style.display="none"
document.querySelector('[class^=textArea-]').appendChild(fakeSpan)

can solve this problem temporarily

Conclusion

I am not pretty sure whether only I meet this in Canary as @BobbyWibowo said "unable to replicate this till now, in Canary"
Although I disabled all of my plugins and themes in Canary, the Dom is still like the screenshot shown above. Hence, I think maybe the original Dom in Canary 124017 may like above.

Sorry, I miss the message that you also encountered this
"encountering it on my end too"
Therefore, it might caused by new version of canary.

Maybe there is any better discord api can tell which discord client are using, and try to fix this issue by the stuff just like if "canary" else ... ?

Canary 124017 (2c2001f)

In which OS did you get this Canary build?
It might have been a temporary update to use <textarea/>

On my Windows boot, my Canary build is at Canary 124157 (ad7bbc4), and it's using <div></span></div>, just like in Discord Stable

Ah, I might have worded it wrong
I meant that I still had not encountered the issue, even in Canary, so I could not be sure if the workaround would work fine

Canary 124017 (2c2001f)

In which OS did you get this Canary build? It might have been a temporary update to use <textarea/>

Windows 11 Home 21H2 22000.613

Because my Canary version num (124017) seems to be lower than yours (124157).
I just tried to reinstall Canary, and the version num became Canary 124163 (9d74307) which is bigger than 124157 as well as 124017.
Still I get textarea in message sending box

[BobbyWibowo]

I figured it out

Discord uses <textarea/> when this option below is turned off

I will make a pull request containing a fix soon

[NawaNae]

Thanks a lot. Then I just trun this switch on for a temporary solution.
