Fatal error on unique constraint

I'm using postgres in the context of a Remix application using Drizzle.

CREATE TABLE public.nouns (
    id varchar(13) NOT NULL,
    singular varchar(128) NOT NULL,
    plural varchar(128) NOT NULL,
    french varchar(128) NOT NULL,
    CONSTRAINT nouns_pkey PRIMARY KEY (id),
    CONSTRAINT nouns_singular_unique UNIQUE (singular)
);

I have an unique constraint on singular. When trying to insert a duplicate value, instead of a database error I could catch, I have the following fatal error:

node:internal/fs/utils:347
    throw err;
    ^

Node.js v18.14.1

{
    "drizzle-orm": "^0.29.3",
    "postgres": "^3.4.3",
}

Using a SQL client leads to the expected error message:

SQL Error [23505]: ERROR: duplicate key value violates unique constraint "nouns_singular_unique"
  Detail: Key (singular)=(das Buch) already exists.
