Share the http call that’s causing it. Could also be a DNS thing. Are you trying to call an internal site or something that won’t be in public DNS?

@PNJ Yes, that's an internal site.

<http://http.post|http.post>({
                url: '<http://example.com>',
                headers: { 'Content-Type': 'application/json' },
                body: { data: body }
            })

You’re trying to call a URL on an internal site? It won’t work. UE scripts are executed on the NetSuite server

@PNJ can I use clientscriptmodulepath? any other idea?

@ali are you calling Suitelet or Restlet ?

it's not a netsuite endpoint

Did you test with any third party clients ?

yes

are you passing authorization ?

as pnj said issue is that's an internal site

Got it

any solution?

@Ali why don’t you use https.post ?

An "internal site" that is not publicly accessible from the outside will not be "seen" by Netsuite so any script running to connect using either the N/http or N/https modules will not work. You have to ensure that your "internal site" has a publicly accessible IP address so that Netsuite can connect to it.

I think if it is hosted outside netsuite then its not internal
