Unable to retrieve config data from HC Vault in Scala

[pforpramit]

I am using below code to read config data from HC Vault,

package com.dell.eventreader.config
import com.bettercloud.vault.json.Json
import com.bettercloud.vault.{Vault, VaultConfig}

object VaultConfig {

  def main(args: Array[String]): Unit = {
  
    // Configuration properties
    val host = "vault.com"
    val port = 443
    val scheme = "https"
    val namespace = "my/namespace/path/"
    val roleId = "sample-role"
    val secretId = "sample-secret"

    // Initialize Vault configuration
    val vaultConfig = new VaultConfig()
      .address(s"$scheme://$host:$port")
      .nameSpace(namespace)
      .build()

    // Create a Vault client
    val vault = new Vault(vaultConfig)

    // Specify the path to the secret in Vault
    val secretPath = "/kv/data/scala-poc"

    // Authenticate using role ID and secret ID
    vault.auth().loginByAppRole(roleId, secretId)

    // Read the secret from Vault
    val response = vault.logical().read(secretPath)

    // Extract the configuration from the response
    val configMap = response.getData

    println("Retrieved configuration from Vault:")
    configMap.forEach((key, value) => println(s"$key -> $value"))
  }
}

There is no error, but it does not print any config data either. However, there are some config data as I can see from Vault UI. There, the navigation goes like - namespace-path -> kv -> scala-poc

As there is no error shown, I suppose the Vault configurations are correct and have been set correctly as well. I am unsure of what will be the correct secretPath if not this one. Tried with /kv/scala-poc as well, but no luck. Also, I don't find anything to set kv as backend here. I can confirm that kv version 2 is being used this side.

Unable to identify what's missing in here.
