I meet a error:

/root/nodePage/node_modules/mongoose/node_modules/mongodb/lib/mongodb/connection/base.js:242
throw message;

DEBUG: Program node app exited with code 8

I checked there is the collection "counters" and a document { "_id" : ObjectId("53271980a811715413c98408"), "model" : "customerunikey", "field" : "id", "seq" : 10002, "__v" : 0 }.

how to fix the error, please?
