When trying to start JWP process there is an error in the log:
U00029402 An error occurred during artifact generation: java.security.InvalidKeyException: IOException : DER input, Integer tag error
Release : 21.x
Component : Automic Workload Automation
Wrong keystore format used.
Change of public/private keys - in this case PKCS#8 to supported PKCS#12 helped to solve the issue.
