I have a fresh docker installation of Passbolt 5.5 which cannot generate the shared metadata keys.
In the organization settings > Metadata key, I try to generate a key (Created: Pending) as demanded but upon saving, an error is raised and the key not saved:
{
"code": 400,
"body": {
"metadata_private_keys": {
"_empty": "The metadata private keys should not be empty."
}
}
}
I couldn’t find any solution. All other issues (GPG server key, JWT tokens etc.) are resolved.
