Simple repro:

    .post('/api/uploads/:id', async (req) => {
        let { id } = req.params;
        let store = Kv.openDefault();
        try {

            const bodyBytes = new Uint8Array(await req.arrayBuffer());
            console.log(`[api]: Starting upload for ${id} with size ${bodyBytes.byteLength}`)
            store.set(`zip-${id}`, bodyBytes);
            return new Response('OK', { status: 200 })
        } catch (e: any) {
            console.error(`[api]: Error uploading for ${id}: ${e.payload}`)
            return error(500, `Internal server error.`)
        }

    })

This will be fixed by the upcoming release based on bytecodealliance/ComponentizeJS#184

[radu-matei]

ComponentizeJS PR has been merged 🎉

Once we have a release, I would like to have a patch release that includes this and #326.

What do you think?

[ThorstenHans]

Awesome, cutting a release including this and #326 would be awesome. (cc @karthik2804 for viz)
