Hello Jeff. Sorry, this is not a Docker based install. I used bitnami on google cloud. Since I saw the exception coming from change in the values of mene items from Basic Setup Configuration, I thought, I will post it here.
I removed all the entries in the Top Menu and I tried to save it. If it is instance specific, I will take it up with Bitnami forums (where one of suggestions is to reinstall the setup). I wanted some more details on this.
