Android Question jRDC2 server with stored procedures, I can't get values

[Carlos Mojica]

Following https://www.b4x.com/android/forum/t...ith-stored-procedures-support.123294/#content, I can't get the return values.

Dim req As DBRequestManager = B4XPages.MainPage.jrdc.CreateRequest
Dim cmd As DBCommand = B4XPages.MainPage.jrdc.CreateCommand("insertarUsuario", _
            Array(edtContrasena.Text, edtNombre.Text, edtCorreo1.Text, CreateMap("name":"varResponse", "type":"OUT", "sqlType":"VARCHAR")))
Wait For (req.ExecuteCall(cmd, 0, Null)) JobDone(j As HttpJob)
If j.Success Then
        Log("Call executed successfully")
        req.HandleCallJobAsync(j, "req")
        Wait For (req) req_CallResult(resultSets As List, parameters As Map)
        'Let's print out the returned result sets. resultSets is a list containing 0 or more DBResult objects.
        For Each res As DBResult In resultSets
            req.PrintTable(res)
        Next
        'Let's print the returned OUT parameters
        Log($"Parameters map content: ${parameters}"$)
    Else
        Log($"ERROR: ${j.ErrorMessage}"$)
    End If

The code never end the Wait for (never reach the "if j.Success then"), but the server does its job. The stored procedure is:

CREATE PROCEDURE insertarUsuario(
    IN  claveP BLOB, nombreP VARCHAR(250), usuarioP VARCHAR(150), 
    OUT varResponse LONGTEXT)
BEGIN
    # Revisamos si existe el usuario
    DECLARE idP Int;
    DECLARE tokenP VARCHAR(1500);
    
    SELECT idusuario, token
    INTO idP, tokenP
    FROM usuario
    WHERE usuario = usuarioP;

    IF (idP is null) THEN
        insert into usuario    values(null, nombreP, AES_ENCRYPT(claveP,"XXX"), usuarioP, UUID(), NOW());
        SELECT idusuario, token
        INTO idP, tokenP
        FROM usuario
        WHERE usuario = usuarioP;

        SET varResponse = CONCAT('{"idP":',idP,', "tokenP":',tokenP,'}');   
    ELSE
        SET varResponse = '{"idP": -1, "tokenP": -1}';           
    END IF;
    
    SELECT @varResponse as response;    
END

Thanks in advance
