Socket Hangup Error when connecting Oracle NoSQL kvstore - node.js

Question

I had an issue in nodejs, when I use the API link https://hostname:8089
return new NoSQLClient({
serviceType: ServiceType.KVSTORE,
endpoint: 'localhost:8089'
});
I'm getting error like this,
Error: [REQUEST_TIMEOUT] Operation timed out after 10000 ms and 6 retries; Caused by: [NETWORK_ERROR] Network error; Caused by: socket hang up

Answer 1

There is nothing wrong with the query, it's about the port, you have to expose the port first and then try it...or disable the firewall

Answer 2

This error happens when you are trying to access a secure KVStore using a non-secure connection call ( http://localhost:8089 )
NoSQLTimeoutError: [REQUEST_TIMEOUT] Operation timed out after 10000 ms
and 6 retries; Caused by: [NETWORK_ERROR] Network error;
Caused by: socket hang up
When accessing a secure KVstore, you need also to provide a user/pwd. If not, you will have the following error
NoSQLArgumentError: [ILLEGAL_ARGUMENT] TABLE_REQUEST: Illegal Argument:
Missing authentication information
Here is an example of a connection string (see https, if this value is not set you will use http by default):
return new NoSQLClient({
serviceType: ServiceType.KVSTORE,
endpoint: 'https://localhost:8089'
, auth: {
kvstore: {
user: "driver_user",
password: "DriverPass##123"
}
}
});
In a secure mode, the proxy requires an SSL Certificate and private key. You need to provide the certificate, before running your application, set the environment variable NODE_EXTRA_CA_CERTS
export NODE_EXTRA_CA_CERTS=<yourpath>/certificate.pem
Without the certificate, you will have the following error:
NoSQLAuthorizationError: [REQUEST_TIMEOUT] Authorization error:
[operation timeout]: Failed to login to kvstore.
Operation timed out, see the cause
You also need to validate the requested domain name to match the server's certificate.
$ curl --cacert ~/certificate.pem https://localhost:8089
curl: (51) Unable to communicate securely with peer: requested domain name
does not match the server's certificate.
In this case, you need to change the certificate or use the appropriate URL
$ openssl x509 -text -noout -in ~/certificate.pem | grep CN
Issuer: CN=kvlite
Subject: CN=kvlite
$ curl --cacert ~/certificate.pem https://kvlite:8080
If your CN is not localhost, use an url matching with the certificate (e.g.)
return new NoSQLClient({
serviceType: ServiceType.KVSTORE,
endpoint: 'https://kvlite:8089'
, auth: {
kvstore: {
user: "driver_user",
password: "DriverPass##123"
}
}
});
