It will cause my server code to crash, I need to write a wrapper function to use it, like:

export function safeOnServerPrefetch(fn: () => any) {
    onServerPrefetch(async () => {
        try {
            await fn();
        } catch (e) {
            console.log('Running onServerPrefetch error:', e);
        }
    });
}

I'm experiencing this same issue. I'm actually trying to throw a custom Error from OnServerPrefetch and stop the execution of the component immediately. But it's impossible since Vue/Node will crash in a somewhat random spot even though I have try-catch on higher levels. The "random" crash place seems to be around executing: let template = await fs.readFile(path.resolve(__dirname, templateName), 'utf-8');
