Jenkins and plugins versions report

Environment

Jenkins: 2.492.2
OS: Linux - 6.8.0-52-generic
Java: 17.0.11 - Eclipse Adoptium (OpenJDK 64-Bit Server VM)

credentials:1413.va_51c53703df1

What Operating System are you using (both controller, and any agents involved in the problem)?

Reproduction steps

1. Navigate to Manage Jenkins > Credentials > System > Global credentials
2. Click +Add Credential
3. Select Kind -> Vault-Username-Password Credential
4. Select Scope -> Global
5. Set Prefix Path -> ibmcloud/kv
6. Set Path to <SECRET_GROUP_ID>/<SECRET_NAME_OR_ID>
7. Specify Username and Password keys
8. Set K/V Engine Version -> 2
9. Set some ID
10. Click Test Secret Vault retrieval button

Expected Results

Successfully retrieved username <MY_USERNAME> and the password

Actual Results

FAILED to retrieve username key: com.datapipe.jenkins.vault.exception.VaultPluginException: Key username could not be found in path <SECRET_GROUP_ID>/<SECRET_NAME_OR_ID>

Note: prefix path is not added to path

Anything else?

When specifying Path as ibmcloud/kv/<SECRET_GROUP_ID>/<SECRET_NAME_OR_ID> and leaving Prefix Path either empty or setting it to ibmcloud/kv in the credential definition (it's also specified in the Plugin settings though), the call is successful!
I just don't think that's the expected behaviour.

Are you interested in contributing a fix?

I believe adopting the IBM Cloud Secrets Manager will be a big task and necessary to create a smooth interaction with the HashiCorp Vault Jenkins plugin and I don't have the required expertise for this. I would still very much appreciate your support
