E8104 error

saved.bind defaults type contains Secret<…>

area: stdlib (x8xxx)
fails the build: yes

The type of the defaults given to saved.bind contains a Secret<…> type, somewhere inside it (the message names the field). Secret values can't be compared or saved: the module drops them at logout, so such a field would never keep its value.

Store a plain value type instead, and keep secret values in memory only.

The compiler reports it like this:
