javascript - TypeError: Cannot read property 'split' of undefined | Schema issue? -


i cannot read property 'split' of undefined when following code:

router.get("/startup/:id", function(req, res) {     // uses id in url find id in      // database passes data foundstartup     startup.findbyid(req.params.id).exec(function(err, foundstartup){         if(err) {             console.log(err);         } else {             var split = foundstartup.aboutstartup.techstack.split(",");             res.render("startup/show", {startup :foundstartup, split: split});         }     }); });

it used work went , removed '_' schema , therefore everywhere had schema called. have no idea why error pop now. have gone through every file created project , nothing left old references. have spent 2 ish hours on google , stackoverflow looking @ others solutions , none have worked me code started used work.

suggestions on solutions? maybe should add error checking instead of later?

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
