Thank you for the advices, I am new to the area of programming so maybe I did not explain my problem. When I am executing my code it prints on the terminal:

Problem with session get request: The OBJECT IDENTIFIER value "ARRAY(0
+x942c50)" is expected in dotted decimal notation.

While I was trying to debug my code, I put a print Dumper(\$session); so I could actually see in further analysis what is happenning. When I did that I saw on the terminal:

$VAR1 = \bless( {
                   '_translate' => 0,
                   '_security' => bless( {

At this point I saw the funny characters. Based on experimentation I found the error. I did not know include the request:

push (@request, ($sysDescr,$sysUpTime));

$output = $session->get_request(
   -varbindlist => [\@request] ,
);

When I removed the "\" it works just fine. I can not exaclty understand the error or the reason but based on what I have read is the reference on the hash.

Based on the documentation from CPAN

"This list is passed to the method as an array reference using the -varbindlist argument."

But I can not completely understand why if I remove the "\" it works.

Thanks in advance for your time,advices and assistance to my query
