Go: How to pass jsonb argument in a PG query?

Question

I wrote a PG query (a function) which takes in an argument (jsonb).

This works when I run the query through pgAdmin:

SELECT * FROM f_get_profiles(
    '[{"role": 1, "experience": 1 }]'::jsonb, 
    array[2]::int[],
    array[1]::int[],
    10, -- limit 
    0   -- skip 
)

And this returns me 3 records from the DB.

But I am unable to do the same using go code:

    q := `
        SELECT * FROM f_get_profiles(
            $1::jsonb, $2::int[], $3::int[], $4, $5
        )
    `
    rows, pgErr := p.db.Query(q, f.Expertise, pq.Array(f.Languages), pq.Array(excluded), limit, skip)
    if pgErr != nil {
        return nil, logAndReturnError(pgErr, "Unable to get profiles using the filters")
    }

The go types of arguments passed are:

f.Expertise : json.RawMessage
f.Languages : pq.Int32Array 

I wonder what I am doing wrong. I am not getting any array but this is returning empty result.

More details on how I am accessing the rows:

var profiles dto.ProfileSuggestions = dto.ProfileSuggestions{}
for rows.Next() {
    var p dto.ProfileSuggestionsNode
    err := rows.Scan(&p.UserId, &p.Username, &p.Photo, &p.About, &p.Languages, &p.Expertise)

    if err!=nil{
        return nil, logAndReturnError(err, "Unable to scan the profile")
    }
    profiles = append(profiles, p)  
}
