why it won't work in Vercel production environment? very strange

[jcyuan]

my provider:
<PlausibleProvider manualPageviews={true} selfHosted={true} enabled={true} taggedEvents={true} domain={config.domainName} trackLocalhost={true} />

but it only works at my local env (for both run dev and run build && start), when i publish my project to Vercel, it won't work anymore, but the response is still ok in the Response tab the same like what i get from local env from /proxy/api/event, so really not sure what happend....

parameters are correct, and response is correct too, just nothing appear in Plausible's dashboard.....
