HashiCorp Credentials provider error when using -runner uber jar

[elmarm88]

I have a small POC java app that has a db password stored in a HashiCorp vault.

I use it as a credentials provider in quarkus.

quarkus.datasource.soam.db-kind=oracle
quarkus.datasource.soam.jdbc.driver=oracle.jdbc.driver.OracleDriver
quarkus.datasource.soam.jdbc.url=jdbc:oracle:thin:@localhost:1521:CUSTOMD
quarkus.datasource.soam.username=soa_metadata
quarkus.vault.credentials-provider.soam.kv-path=myapps/vault-quickstart/soametadata
quarkus.datasource.soam.credentials-provider = soam

If I run the it from command line with

mvn quarkus:dev

it all works fine.

However if I run the -runner jar file in the /target directory (its an uber-jar) with the following command :

java -jar poc-quarkus-vault-db-runner.jar

I get the following error:

2022-12-06 12:23:59,870 WARN  [io.agroal.pool] (agroal-11) Datasource 'soam': Failed to create connection due to VaultClientException
2022-12-06 12:23:59,883 ERROR [sun.java.ws.rest.quarkus.poc.api.personinf.DbInfoService] (executor-thread-0) Error point 1: null: io.quarkus.vault.runtime.client.VaultClientException code=404 body={"errors":[]}

I should note that the app starts up fine, its just when I call the REST endpoint to pull something from the DB that is crashes.
Any ideas would be very welcome.

Thank you in advance
