unable to encode []model.Field into text format for unknown type (OID 16385): cannot find encode plan

What happened?

I am trying to create a query that will return a set of results based on a dynamic filter.
I am using the pattern described here: #364 (comment)
However, the query fails due to my ENUM.

I want the query to return any results where the color is any of the filtered colors.
If I change the query to fav_color = @fav_colors::COLORS, then the query works.
But it doesn't seem to like it when using the ANY(@fav_colors::COLORS[]), even though that pattern does work with the regular text/varchar field.

The error message:
&fmt.wrapError{msg:"failed to encode args[5]: unable to encode []model.Colors{\"red\", \"blue\", \"green\"} into text format for unknown type (OID 16385): cannot find encode plan", err:(*fmt.wrapError)(0x14000092620)}

Example calling code:

	accounts, err = dao.SelectAllAccountsByFilter(ctx, model.SelectAllAccountsByFilterParams{
		AnyNames:    true,
		Names:       []string{"Jane", "John"},
		IsActive:    true,
		Active:      true,
		AnyFavColor: true,
		FavColors:   []model.Colors{model.ColorsRed, model.ColorsBlue, model.ColorsGreen},
	})
	if err != nil {
		fmt.Printf("%#+v\n", err)
	}

Database schema

CREATE TYPE COLORS AS ENUM('red', 'green', 'blue');

CREATE TABLE accounts (
    id          BIGSERIAL PRIMARY KEY,
    name        VARCHAR(50)              NOT NULL,
