@wan , thanks for your reply. I went to India for vacation and struck there due to some issue. Back to USA now. I noticed that, My team has tried and these and finally they went with Manual encryption approach. seems FLE never worked on Java on the server. it is still working fine on Developer machine. problem with only server.
Our Base image is redhat/ubi8.
Same redhat base image is works fine on .NET core " redhat.io/ubi8/dotnet-60:6.0-20.20221101102142
problem is only on Java side " redhat.io/ubi8/openjdk-8:1.14-3.
please provide how to debug further. or we should use only Manual encryption on Java ?
