This lead us to find Oracle documentation on the errors and highlighted an extra Patch that looks to be required.
https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=375573192164768&id=2939068.1
The issue was that an existing Oracle Notification Service (ONS) bug/fix was missed and not rolled up into the DBc 19c track. As such, the WebLogic Plugin is not able to properly handle the chunked response over SSL.
This was released in the following Patch - https://support.oracle.com/epmos/faces/PatchDetail?_adf.ctrl-state=19zj90w2rq_4&patchId=35333510&_afrLoop=375570746737057
Testing
This patch was applied to a server manually and once OHS was restarted we no longer saw issues with Curam.
The changes in this PR adds this new patch and ensures it is applied when deploying
Testing has been completed locally and all molecule tests have passed.
Backup
Similar errors were also seen in this Oracle support Doc - https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=376719113206821&id=3041758.1
It is suggested here that the flow for installing 19c was the cause but i believe we are following the expected process so this is not the cause of the issue above.
