I am trying to find documentation to configure Vault Certificate credential but unable to get one. 

I have updated below but getting exceptions like below with different combinations, 

ex: 

Namespace: <no-value>

Prefix path: <no-value>

Path:

1. tried giving vault secret path not worked
2. tried giving pem file path(/tmp) from Jenkins master not worked

KeyStore Key:

1. Provided /tmp/<pem filename> 
2. Provided <pemfilename>
3. Pem content

Password Key:

1. Password of the encrypted pem file

FAILED to retrieve keyStore key:
com.datapipe.jenkins.vault.exception.VaultPluginException: could not read from vault: java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 at path: --> when i try to provide path as empty and keystore key as filename of pem file used to authenticate and password key as password to decrypt the pem key

FAILED to retrieve keyStore key:
com.datapipe.jenkins.vault.exception.VaultPluginException: Key accmvault-jenkinsuat.pem could not be found in path /tmp --> tried with /tmp in keystore key and password in password key
