Switching between Kendra and Classic DUS mode

[alexchirayath]

Describe the bug Currently when I switch from the classic DUS mode to Amazon Kendra enabled version (or vice cersa), the changes are not reflected on the UI even though the infrastructure pieces are updated.

To Reproduce Switch the enableKendra flag in package.json file Redeploy on existing stack

Expected behavior Seamless transition between the 2 DUS modes after redeploy
