Compiler crashes with dymamic imports (`IllegalStateException`) about closure-compiler HOT 3 OPEN

Dynamic imports are only supported if the output chunk type is ES_MODULES. This works:

$ echo 'const x = async () => { const buffer = await import(/** @type {string} */("buffer")); alert("1", buffer);}; x();' | google-closure-compiler -W QUIET --module_resolution WEBPACK -O ADVANCED --chunk_output_type ES_MODULES
The compiler is waiting for input via stdin.
(async()=>{const a=await import("buffer");alert("1",a)})();export{};

The crash is not great, though. Would be nice if there was a good error message that mentioned the chunk type requirement.

Thanks, I'll see if that works in my application.

Hm, that may be a design decision you've made and I'm fine leaving it at that. However, dynamic imports are, in principle, allowed everywhere (providing support for import, of course). E.g., <script>import('foo').finally(()=>alert("Yay!"))</script> is perfectly valid, no need for <script type="module"> there.

It works in v20230502 and before, but it fails from v20230802. Hope this issue can be resolved soon.
