TrueNAS Scale electric eel app Vaultwarden v1.32.1 fails to deploy after updating from v 1.0.4

I am running TrueNAS-24.10.0 and VaultWarden v 1.0.4
I selected to upgrade VaultWarden to v 1.32.1
After successfully downloading, the new version failed to deploy.
The logs show “connection to server at “postgres” (172.16.1.2), port 5432 failed: FATAL: password authentication failed for user “vaultwarden”\n”"
Editing the setup shows the same password I have been using. I have not changed the password.
After rolling back the upgrade VaultWarden v 1.0.4 deploys without a problem.
I expected the new version would pickup the existing settings including the password. If not, how can I reset the password without losing my data? Do I have to export, delete the app, reinstall the latest version then import the data?
Any advice would be much appreciated - I do like to keep up to date with bug fixes and security patches with software like this - helps me sleep at night. TIA
