FglAM does not start after a failed upgrade attempt - Error : KeyStoreManagerException: Failed to (4333492)

The FglAM upgrade failed in the middle due to an out of disk space situation. The following error was displayed when trying to start the FglAM

The FglAM upgrade failure left the credentials.keystore file empty

./state/default/credentials:
-rw------- 1 pipmp01 dipm 0 Oct 3 11:36 credentials.keystore

Since the file had a 0 byte size (empty) it triggered a path in the code that “if the file exists, read it”. This caused the failure with the error

The same code path states “if the file doesn’t exist, create it” so the solution is to remove this file, and allow FglAM to recreate it.

1) Navigate to the Client where the FglAM is installed

2) Delete the 0 byte size file

FglAM/state/default/credentials/credentials.keystore

3) Start the FglAM
