Similar to this users issue (https://community.oracle.com/tech/developers/discussion/4294722/using-proxy-users-w-vs-code#latest) I am having problems connecting where the proxy password section is empty. I also tried the connection string provided (User Id=myuser;Data Source=dbhostname:1521/DBSERVICENAME;Proxy User Id=myproxyuser;Proxy Password=myproxypass;)
I also tried using this following connection string
(User Id=myuser; Password=mypassword; Data Source=dbhostname:1521/DBSERVICENAME;Proxy User Id=myproxyuser;Proxy Password=;)
This threw me the error of no empty proxy password. I tried using several combinations but eventually locked our schema which was not an enjoyable experience to get fixed. Using the standard advanced connection the proxy requires input to create the connection thus having to move to the connection string.
As well as the above attempts I have tried using the username[proxy] with no luck. It also seems my google-fu is failing me.
Any help would be appreciated.
