Unity : WebGL html5を動かしてみる！ gzipが？色々なエラーの末？

WebGLでビルドしたものをそのままサーバーに載せました。

Unable to parse Build/html5.framework.js.gz! This can happen if build compression was enabled but web server hosting the content was misconfigured to not serve the file with HTTP Response Header “Content-Encoding: gzip” present. Check browser Console and Devtools Network tab to debug.

というエラー。

WebGL: サーバー設定コードサンプル - Unity マニュアル

The code samples below show how to configure your server when working with WebGL. The following samples apply to Nginx, Apache, and IIS servers. For further inf...

# On-disk Brotli-precompressed data files should be served with compression enabled:
location ~ .+\.(data|symbols\.json)\.br$ {
    # Because this file is already pre-compressed on disk, disable the on-demand compression on it.
    # Otherwise nginx would attempt double compression.
    gzip off;
    add_header Content-Encoding br;
    default_type application/octet-stream;
}

# On-disk Brotli-precompressed JavaScript code files:
location ~ .+\.js\.br$ {
    gzip off; # Do not attempt dynamic gzip compression on an already compressed file
    add_header Content-Encoding br;
    default_type application/javascript;
}

# On-disk Brotli-precompressed WebAssembly files:
location ~ .+\.wasm\.br$ {
    gzip off; # Do not attempt dynamic gzip compression on an already compressed file
    add_header Content-Encoding br;
    # Enable streaming WebAssembly compilation by specifying the correct MIME type for
    # Wasm files.
    default_type application/wasm;
}

# On-disk gzip-precompressed data files should be served with compression enabled:
location ~ .+\.(data|symbols\.json)\.gz$ {
    gzip off; # Do not attempt dynamic gzip compression on an already compressed file
    add_header Content-Encoding gzip;
    default_type application/octet-stream;
}

# On-disk gzip-precompressed JavaScript code files:
location ~ .+\.js\.gz$ {
    gzip off; # Do not attempt dynamic gzip compression on an already compressed file
    add_header Content-Encoding gzip;
    default_type application/javascript;
}

# On-disk gzip-precompressed WebAssembly files:
location ~ .+\.wasm\.gz$ {
    gzip off; # Do not attempt dynamic gzip compression on an already compressed file
    add_header Content-Encoding gzip;
    # Enable streaming WebAssembly compilation by specifying the correct MIME type for
    # Wasm files.
    default_type application/wasm;
}

サンプルの通り、これを入れまして gzipはOK

次なるエラー

Uncaught (in promise) RangeError: Maximum call stack size exceeded

こちらは、キャッシュのせいでした。
