    I have a published game that I wanted to update today, made a WebGL build as always, uploaded to the server, everything worked but noticed I didn't update some of the data (just changing strings in ScriptableObjects). Quickly updated around 20 strings and since then I'm unable to build a working WebGL build of that project. The error I'm getting is 

    UnityLoader.js:4 failed to asynchronously prepare wasm: LinkError: WebAssembly.instantiate(): table import 1 is smaller than initial 104523, got 104402
    
LinkError: WebAssembly.instantiate(): table import 1 is smaller than initial 104523, got 104402


    I'm getting the same result building it on 2018.4.26f1 and 2018.4.27f1
    Can anybody help me solve that?

    This suggests that the cached game content may have gone out of date somehow. Try clearing browser cache, or test on a browser that has not visited the page before?

    Is there a way to clear the cache from the unity/webgel side? This is a pain in the ass when deploying new test builds and trying them out.

    I have the same error in some PC's. This is what is seen in the console. I've tried clearing the browser cache, but it doesn't help. Also tried from different browsers, those that have not visited the page, they have the same error.

    Other thing is, this only occurs on some PC's. It works without flaw on others.
    Please help!

    Here's an update: In the build settings, Code Optimization was set to "Size", then I changed to "Speed" and it was fixed. Unity v2020.2.5f1

    Hi. Where did you find this setting? I look all over Unity, including inside Build Settings and couldn't find anything that would say "Code Optimization" and then "Speed" or Size". Specifically installed and updated my project to Unity 2020.2.5f1 to try this.

    I am having this issue after trying to update a build on ftp server, only that I am having it everywhere, not only specific PCs. It goes something like this:

    
WebGLBuild1.loader.js:1 wasm streaming compile failed: LinkError: WebAssembly.instantiate(): table import 1 is smaller than initial


    Any help would be very appreciated, thank you.

    Having this issue in 2021.1.22f1, setting Code Optimization to Speed seemed to have fixed things for a few builds but now shows whether Speed or Size is selected.

    We get the error 
    Uncaught RuntimeError: null function or function signature mismatch
    on 2021.3.5f1, and the issue is resolved when we set Code Optimization to Size.
    We don't see it in development builds, and we weren't seeing this on earlier versions.
    We'd really like this to be fixed, since it increases our build size by over 1mb, which is really nasty on web.
