What does "wasm streaming compile failed" warning mean?

Running the library on Chrome or Safari, you may have noticed the following error:

wasm streaming compile failed: TypeError: Failed to execute 'compile' on 'WebAssembly': Incorrect response MIME type. Expected 'application/wasm'., falling back to ArrayBuffer instantiation.

Please feel free to ignore this.  It refers to streaming compilation that is currently only supported on Firefox. On other browsers, we fall back to a different method.

This should not impact your ability to load the library and scan.

However, if you cannot scan with your implementation, you can check out this article.
