Implement a Better Try-Catch logic with Counter for Scripts with API invoking Network/Remote calls

Here is a sample snippet of how to implement a better try-catch logic (with counter parameter) to be able to control how many times to retry a request. This is useful for scripts with API invoking Network/Remote calls (ex. nlapiRequestURL, nlapiXMLToPDF).

var counter = 1; var exit = false; do { try { var outXMLFile = nlapiXMLToPDF(outXML); if (outXMLFile!= null && outXMLFile!= undefined) { exit = true; break; //exit try-catch and do-while loop } } catch(error) { if ( error instanceof nlobjError ) { counter += 1; nlapiLogExecution('ERROR','Process Error', error.getCode() + ': ' + error.getDetails()); } else { nlapiLogExecution('ERROR', 'Unexpected Error', error.toString()); exit = true; break; //exit try-catch and do-while loop } } } while (exit == false && counter <= 3) // in case of SSS Error, do the request again at least 3 times
