WebAssembly.instantiateStreaming failed because your server does not serve wasm

I keep getting this in the console and it’s triggered by a JS file in Pattern CSS

WebAssembly.instantiateStreaming failed because your server does not serve wasm with application/wasm MIME type. Falling back to WebAssembly.instantiate which is slower. Original error:
TypeError: Failed to execute ‘compile’ on ‘WebAssembly’: Incorrect response MIME type. Expected ‘application/wasm’.

Not faulting the plugin at all. I’m sure I need to mod PHP or Apache on my server. Just documenting it here. I’ll follow up when I resolve.
