pub const DUPLICATE_VALUE_MESSAGE: &str = "A duplicate value for a field with unique values was provided";Expand description
The one message a duplicate-key collision ever carries (MongoStorageAdapter.js:576-579).
Fixed, and the same string in both upstream adapters. Which field collided travels in
ParseErrorInfo::duplicated_field instead, because the driver’s own text names the database
and the value that collided.
