Explicitly defining data type, but get: "could not determine data type of parameter $1" #3166

Version

1.25.0

What happened?

Hi, thanks for contributing to such an awsome library.
I'm trying to define explicit data types in my query, but I keep getting "could not determine data type of parameter $1" error.
My code:

-- name: ScanReports :many
SELECT *
FROM reports
WHERE 
ST_DWithin(
    point,
    ST_Point(@lat::DOUBLE PRECISION, @long::DOUBLE PRECISION, 3857),
    @radius::DOUBLE PRECISION
)
AND region = $4
AND occur_at >= $5
AND occur_at <= $6
ORDER BY occur_at
LIMIT $7;

instead of DOUBLE PRECISION, I've also tried: float, text. Nothing works.
I'm not sure how this feature is supposed to work since documentation doesn't elaborate, so I might be completely using it wrong.
Thank you.

Note: I'm using sql_package: "pgx/v5", which I can't add to playground.
