node.js - Error Handling with nested catch -


i encountered problem during error handling in presence of several catch nested, because object response called more times.

objecta.create({}) .then(function (objecta) {    objectb.create({     objectaid: objecta.id,     name: objectadata.name,     cropid: objectadata.crop })   .then(function (objectb) {     objectadata.collection.foreach(function () {         objectc.create({           objectbid: objectb.id,       })         .catch(function (err) {             console.log('# # # catch 1 # # #');             next({status: 500, data: err});         })     }) })   .catch(function (err) {       console.log('# # # catch 2 # # #');       next({status: 500, data: err});   });    //response http 200   next({status: 200, data: objecta.id}); }) .catch(function (err) {   console.log('# # # catch 3 # # #');   next({status: 500, data: err}); })

this happens when there's error inside catch (for example # catch 2 #) , next({status: 500, data: err}); function called next({status: 200, data: objecta.id});

i receive suggestion how handle errors in situation.
