Going to be a update around the image upload situation soon. I expect it tomorrow.

[–] FauxPseudo 2 points 1 year ago

I'm still not having any luck. Any update?

That’s almost always from an endpoint expecting a JSON response but getting back the HTML of a 404 page. Fun!

[–] PugJesus 3 points 1 year ago (1 children)

Don't suppose there's anything to be done on my end to get around it?

That said, I’m not Lemmy support, just a bored web developer.

Some instances are disabling image uploads temporarily until they can deal with the trash that's uploading CSAM.

Not certain if lemmy.world is one of them.

Upload to imgur, copy the image link and post that (the link ending in .jpg/.webp, not the plain imgur link) for the time being.

I tried to do this earlier and I think I messed up, because it was directing off site instead of viewable in Lemmy. Does that mean I likely pasted the link instead of the image?

[–] [email protected] 4 points 1 year ago (1 children)

When you finish uploading you're brought to a full webpage with the image embedded in it like this:

https://imgur.com/a/SzSKW5M

You want to right-click on the image and select 'open image in new tab' which gives you this:

https://i.imgur.com/GFTwYm3.jpg

(if you're on mobile first select 'desktop site' from the browsers options or you'll get a low quality .webp version from the open image button. It'll work, but many ppl hate it)

Finally format it like this to embed it in a post/comment:

![](https://i.imgur.com/GFTwYm3.jpg)

(I added backslashes to the front of that to prevent it embedding the link as an image and show you the formatting instead)

Thank you! This helps

I've been unable to post images since last night as well. Just hopped on my PC to see what the error message was, and it's the same as @tsuica shared:

JSON.parse: unexpected character at line 1 column 1 of the JSON data

Switched to alt accounts on different instances and had zero issues.

[–] Moc 4 points 1 year ago

I have the issue, and it seems to be a HTTP 403 (Forbidden) from CloudFlare.

[–] FauxPseudo 4 points 1 year ago

Can confirm. Same error on two different apps and the lemmy world website.

[–] tsuica 4 points 1 year ago

I can confirm this is the case. Can't upload images to Lemmy.world, getting the same error.

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

[–] Squander 3 points 1 year ago
[–] ChamelAjvalel 2 points 1 year ago

Noticed that about a couple of hours ago...

Also, within Connect for Lemmy, I get

FormatException: Unexpected Character (at character 1)

On Jerboa, I got a whole page of html code, but it vanished too fast for me to be able to remember anything. Also, it has a continual loading icon over the "upload image" icon.

Is good to have multiple accounts, you can also do a backup of your posts and migrate on different istances.

Here is some useful information for people wanting to move instances. For a list of instances, along with with stats for those instances:

Also, tools for migrating instances:

Yes, me as well

[–] Squander 2 points 1 year ago

Came here to ask the same question. +1

[–] Mystech 2 points 1 year ago

Same here. Started sporadically for me starting yesterday. At some point today it became 100% regardless of cache, platform or browser.

[–] Mystech 2 points 1 year ago

Any update on this bug? The imgur hack is fine for image-only posts, but kind of dead in the water for image + url posting.
