Hi chadhasumit13,

Could you please clarify more what are you trying to do?


1) In general, if you simply need a unique id (not necessarily uuid), it 
is better and easier to use request_id variable 
(https://nginx.org/en/docs/http/ngx_http_core_module.html#var_request_id)

you can access $request_id variable by

r.variables.request_id

> external call to an HTTP end-point

2) You can use subrequest method 
(http://nginx.org/en/docs/njs/reference.html#http).

You can find some examples with it here:
