Failed to decompress data for the AssetBundle 'Memory'

Hello.

We got error ”Failed to decompress data for the AssetBundle 'Memory'” when AssetBundle.LoadFromMemory.
How can we solve this? we have no idea...

status:

1. Error causes in WebGL Build with below versions of Unity.
   • 2017.3.0f3
   • 2017.4.1f1
   • 2018.1.0b12
2. No error in Unity 2017.2.0f3 + WebGL Build.
   
3. We are tring to load assetbundle named like "sample/basic/sound/home".
   
4. We have no assetbundle named "Memory".
   
5. No error in other platforms(confirmed in Windows+UnityEditor and Android Build).
6. Other assetbundles named like "sample/basic/textures" are loaded with no error.

Thanks!

Having the same error in my webgl application. I am loading the bundle like this:

Code (CSharp):

1. byte[] decodedBytes;
2.             AssetBundle bundle = null;
3.             try
4.             {
5.                 decodedBytes = Convert.FromBase64String(dataValRaw);
6.                 bundle = AssetBundle.LoadFromMemory(decodedBytes);
7.             }

I'm guessing the error comes from the LoadFromMemory function. Any ideas?

 

The problem was that I didn't specify the options

 BuildAssetBundleOptions, targetPlatform

correctly when building the bundle (uncomopressed and webgl as target).

 

Please do you have some example, i have the same problem, try to convert a byte to assetbundled and then convert into a Gameobject , but when i convert the byte to assetbundle geting a null...

byte[] model = Convert.FromBase64String(sBase64);
AssetBundle bundle = AssetBundle.LoadFromMemory(model);

in the thebuger the variable "bundle" is equals a "null"..

So you have some exmaple o where can i found a examples or any idea T_T please...

 

We get this issue every month or so on some, seemingly random, bundle in our project (a different one every time). The only fix I have found is to change the bundle enough that it works again, possibly by changing a texture to be a slightly different colour or some other action. This is a really time consuming bug. We've had it on most versions since 2017.
