Random undefined response

[krysbzh]

Hello, I'm currently testing the query method of GlideRecord with a demo ServiceNow instance. The server returns the good list of records but sometimes, I receive randomly a value "undefined". Do you encountered the same behavior ? If I resend the request, I receive again the good values.

Thanks in advance

That hasn't happened to me but I'd like to look into it. Which method are you using in GlideRecord?

Sorry for the delay. Here you can see my method ` //Get list of records sn.get('/:table_name', function(req, res) { var tableName = req.params.table_name; var gr = new GlideRecord('demo003',tableName,'itil','itil');

console.log(new Date(), 'In hello route GET / req.query=', req.query);
var result;

console.log("START");

//Champs retournes
if(req.query.returnFields != undefined){
  gr.setReturnFields(req.query.returnFields);
}else{
  gr.setReturnFields('number,short_description');
}

//requete ServiceNow
if(req.query.encodedQuery != undefined){
  gr.addEncodedQuery(req.query.encodedQuery);
}else {
  gr.addEncodedQuery('active=true');
}

//limite du nombre d'enregistrements
if(req.query.limit != undefined){
  gr.setLimit(req.query.limit);
}else{
  gr.setLimit(10);
}

gr.query().then(
  function(value) {
     console.log(value);
     res.json(value);
     console.log("THE END");
  }, function(err) {
    console.log(err);
  })

}); `

Generally, the result is

req.query=' { limit: '2' } START [ { short_description: 'Unable to get to network file shares', number: 'INC0000002' }, { short_description: 'Wireless access is down in my area', number: 'INC0000003' } ] THE END

but randomly, the results is : req.query=' { limit: '2' } START undefined THE END

Apparently older version of the REST API returns undefined for certains conditions. I fixed the readme to include parameter in constructor to specify version
