Thanks!

I've had only success for a few weeks now. I still get the 'An error occurred' message, but even with addons (which include gametest packs) I can upload my world fine.

How I originally came to this:

I removed all resource and behavior packs from my world, and deleted the history json files aswell, then I added all of the addons back manually inside the game. After doing this, my world has had absolutely no issues with uploaded except for the error screen, even though it still uploads.

This isn't the fix for everyone, but it worked very well for me.

Device: Windows 10

Having no issues with my realm, everything working as indented on 1.19.20.

Device: Windows 10

Success! After removing all packs from my world, then adding back some select packs, I was able to upload the world successfully multiple times, with no net limiter or VPN.

After removing all packs from my world, I was able to upload it successfully, but unable to add the packs back on afterwards. 

The netlimiter work-around does not work for me for packs, if anyone finds a way to successfully upload packs, please post a comment!

I tried out the previously mentioned work-around, got NetLimiter and tried a few different upload speeds. I saw some success! As expected, worlds I have with packs that use the Gametest Framework didn't work whatsoever, as Gametest isn't currently supported on realms, but I saw some other success. All worlds I tested (with & without add-ons) worked, the only ones that would not work were ones that have Gametest Framework packs on them, which again, is expected. 

No luck on the main world I've been trying to upload, after updating to 1.19.11.
Device: Windows 10
Experiments: Spectator Mode, Gametest Framework, Holiday Creator Features

Packs: Multiple Behavior packs & Resource packs, one Gametest pack (Upload unsuccessful if all packs are removed from the world file)

Size: 304.4MB

Created originally in 1.18.

I've tested removing packs from a few of my worlds that do not upload, It did fix the issue for some, but for others the issue is still active. 

On a few worlds I've tested, the world has had gametest packs, but others didn't. After removing all packs, I've only had about a 75% success rate, not being able to upload the world I've been wanting to for some time. 

Aside from removing all packs form worlds in-game, I've also edited the world files of some; Removing all pack UUIDs from it's history files, and removing all pack files, with some success. 

I've had absolutely no issues with uploading worlds that only have resource packs on them, or have very little behavior packs, aside from the main world I've been trying & wanting to upload.

Device: Windows 10

more info on unsuccessful worlds: Experiments are enabled (Holiday Creator Features, Spectator Mode, & Gametest Framework) It does have addons packs (but is still unsuccessful if I remove them all). Its just under 400MB in size. Some game settings; things like firetick are off, random tick speed is set at 5 I believe, but nothing else out of the ordinary. 
Also, my world was originally created in early 1.18, is that matters at all.

I’ve had some success with similar experiments and sizes, but I’ve had absolutely no success with the world mentioned above, even after removing all packs and the like.

Reply from @unknown: What are the characteristics of the worlds you are unable to upload, particularly any differences relative to ones that are successful? (Size, game settings, use of particular features, add-ons, anything else.)

Interesting! I'll give that a try! 
Edit: wasn't able to upload anything successfully 
Device: PC / Windows 10

Updated to 1.19.10. Tried to do a few uploads, of a few different worlds, no luck.

edit: success! I've had success uploading one of my testing worlds! It's just over 400mb, and it was made in 1.16 originally. However, this seemed to be a one time thing for this world, after trying again, i am unable to upload it a second time. 

second edit: I'm happy to report another successful upload. It seems the issue may have been me having gametest packs on them, with gametest not being enabled on realms currently.

After some experimentation, I've found some things. When i create a brand new world, it uploads perfectly. If i then add experiments, EDU, and packs to that world, it also uploads great. However, I cannot upload a much larger world (originally made in 1.18) with the exact same experiments on it (but with different packs). I've tried three worlds which are all similar to each other, one made in 1.17, two others made in 1.18, and all three of those will give the 'An Error Occurred' screen when trying to upload them. I've used worlds with different sizes aswell, ranging from 10MB to around 400MB, all from older versions, with no luck. 

I'm on Windows 10, I've tried to upload my world (306.4MB with experiments & addons) a few times today, but I've had no luck. I get the same 'An Error Occurred' screen, and neither my world or addons are uploaded. I'll keep trying a bit more, and send another comment if anything changes.

Edit: I've tested two different worlds with experiments and addons one world i was previously able to upload (in 1.17), and I'm not able to with the new HTTP library. 

Any updates on this?

I've done a little bit of testing with the new HTTP library enabled. I've noticed that any world with Add-ons on them do not work, but worlds without addons do work, at least for me. I've only done this on windows 10, so not sure about other platforms.

I've done a little more uploading with the new HTTP library, my 172.7MB world will not upload, but my 0.31MB world will upload. Both have Holiday creator features and gametest framework enabled, along with education edition. 

After uploading the smaller world, some of the experimental features didn't work anymore. It could be the packs, not sure. The packs i used worked in a regular world, but only kind of worked on the test realm i'm using.

It seems that the smaller world can upload even without the HTTP library enabled.

I've activated the new HTTP library on iOS & Windows, and on 1.18.30 and 1.18.31, i haven't had any success yet. I'll keep trying, and post another comment if i have any luck!

Update: No luck, I've tried multiple times with the new HTTP library on, i've tried on immediate start up, and i've tried with the game open, then closed then i enabled it, then opened the game again, and a few other things, but i've had no success. I've only tried on iOS & Windows though.

Any status updates on this bug? 

meant to put this on the realm bug page.. sry

dang, i meant to make this on realms bugs. sorry ;-;
