I'm having problems running a query that works directly in psql with postgis extension but not with the javascrip pg library connection within a prepared statement.

The query that runs and writes in the database is as follows:

INSERT INTO waps(bssid, strength, "location")
VALUES('T_601', '100', ST_GeomFromText('POINT(38.70722651513132, -9.15248591105515)', 4326));

The table waps has the location column as geometry type.

In my college javascript project I have this section of code returning an error:

        let sql = "INSERT INTO waps (bssid, strength, location) VALUES($1,$2, ST_GeomFromText(POINT($3),4326)) RETURNING id";
        let wapId = await pool.query(sql, [bssid, strenght, location]);

location receives ex: "38.70722651513132, -9.15248591105515", and returns an error:

So why does the query in psql runs normally but when prepared in a javascript environment throws an error?

The problem lies, normally, between the screen and the chair, so any help is appreciated.
