Can't run find

[Bruno Bach]

I'm having trouble doing a basic find.

query := mongo.new_from_json('{}')
count := collection.count_documents(query)
println(count) // 69 return ok

bson_doc := mongo.new_bson()
cursor := collection.find(query)

for cursor.next(&bson_doc) {
   str := mongo.as_canonical_extended_json(bson_doc)
   println(str)
}

it returns me the following error:

mongo.v:19:20: error: unknown function: mongo.as_canonical_extended_json
   17 | 
   18 |      for cursor.next(&bson_doc) {
   19 |       str := mongo.as_canonical_extended_json(bson_doc)
      |                    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   20 |       println(str)
   21 |     }
