Value interpolation fails on CREATE ROLE

Code:

import postgres from "postgres";

const sql = postgres(process.env.DS_DB ?? "", {
    debug: true,
});

const test = async () => {
    const roleName = "test_role";
    const password = "test_password";

    const describeResult = await sql`CREATE ROLE ${sql(
        roleName
    )} WITH LOGIN PASSWORD ${password}`.describe();

    console.log("zz", describeResult);
};

test();

This produces error:

node:internal/process/promises:289
            triggerUncaughtException(err, true /* fromPromise */);
            ^

}

But, if I do it like this:

await sql`CREATE ROLE ${sql(roleName)} WITH LOGIN PASSWORD ${sql.unsafe(`'${password}'`)}`;

then it works and produces valid query ..... LOGIN PASSWORD 'test_password'

Am I doing something wrong?

Reproduce the failing CREATE ROLE example from lib/dbtest.ts and compare the generated query and parameters with the working sql.unsafe example. Trace the query-building entry point shown in the stack trace to determine whether this interpolation case is expected to work, then add or update regression coverage so the intended behavior is clear.
