Error pinging oracle: ORA-12154: TNS:could not resolve the connect identifier specified

[vijay krishna]

I am trying to connect to adb through wallet in oracledb_exporter container and wallet is at /tmp/wallet location.

Below are the debug logs. Unable to understand the issue as first it says successfully connected and then throws the tns error.

time="2022-11-17T11:37:08Z" level=info msg="Listening on :9161" source="main.go:579"

I tried with different DATA_SOURCE_NAME's but all seem to throw the same error. Below is one such data source name that I have tried.
acdc/XXXXXXXXXXX@//vt1jqern.adb.us-phoenix-1.oraclecloud.com:1521/vphbtcf4stcojsp_dvc2687adb324_high.adb.oraclecloud.com?ssl_server_dn_match=false&wallet_location=/tmp/wallet

Any help on this would be much appreciated.
