It depends where you define the models. They should be defined just once otherwise you'll have this problem. In which file you put your definitions? How are you importing this file? If you use it in a function (let's say in /pages/api/myapi.js), try to be sure to not call the definition in the function you export, but do it outside of that function

Hey, make sure to drop the counter collection and try again - worked for me

[eduzera]

@harloom try to check if your collection exist. example:

if(!mongoose.models.account){
  accountSchema.plugin(AutoIncrement,{id:'userId_counter',inc_field:'userId' });
}

ps: to do that you need to remove and create your account collection. ps2: this plugin create one collection called counters, you can check if this collection + field exists there.

i hope it's solve your problem
