Unable to display Flowtrace due to exception while initializing object

It is most likely the issue is caused by missing roles and grants from the system-jazn-data.xml file. Make sure the system-jazn-data has the proper Roles and Grants by comparing with another working environment, if not possible use attached file "system-jazn-data.zip" that contains 2 system-jazn-data to compare, "system-jazn-data_BAD.xml" and "system-jazn-data_GOOD.xml" here you can see the differences between a good and bad one
1.- Stop all servers (admin and managed)
2.- Back up your "<DomanHome>/config/fmwconfig/system-jazn-data.xml" file
3.- Add the missing Roles and grants to the file from a previous backup or another working environment file
4.- start admin and then managed servers
5.- retest the issue

Even after that we observed that issue still persists. then we refer to (Doc ID 1644021.1) where the file DOMAIN_HOME/config/fmwconfig/audit-store.xml is 0 bytes or otherwise corrupted.

To resolve this issue:
1. Stop all the WebLogic servers in the domain, including AdminServer.
2. Restore the corrupted file DOMAIN_HOME/config/fmwconfig/audit-store.xml from a backup. Note that the backup must be the same version, patchset and PSU as the active environment.
3. Start all the WebLogic servers in the domain
