Meteor - insert failed: Method not found - meteor

Question

I have a problem with my Meteor's JS file. I get this error "insert failed: Method not found" when I try to insert any data to the database and reflect on chart. I've tried fetching data directly from db that didn't work too...
thanx in advance.
LinePeople = new Mongo.Collection("LinePeople");
function getRandomInt(min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
}
if (Meteor.isClient) {
console.log("in LIne Client");
//LinePeople = new Mongo.Collection(null);
Template.linenvd3.rendered = function() {
var chart = nv.models.lineChart()
.margin({left: 80}) //Adjust chart margins to give the x-axis some breathing room.
.useInteractiveGuideline(true) //We want nice looking tooltips and a guideline!
.transitionDuration(350) //how fast do you want the lines to transition?
.showLegend(true) //Show the legend, allowing users to turn on/off line series.
.showYAxis(true) //Show the y-axis
.showXAxis(true) //Show the x-axis
;
nv.addGraph(function() {
chart.xAxis.axisLabel('Person number').tickFormat(d3.format('d'));
chart.yAxis.axisLabel('Age (years)').tickFormat(d3.format('d'));
d3.select('#lineChart svg').datum(
[{ values: LinePeople.find().fetch(), key: 'Age' }]
).call(chart);
nv.utils.windowResize(function() { chart.update() });
return chart;
});
Deps.autorun(function () {
d3.select('#lineChart svg').datum(
[{ values: LinePeople.find().fetch(), key: 'Age' }]
).call(chart);
chart.update();
});
};
Template.linenvd3.events({
'click #addDataButton': function() {
console.log(" in line addButton");
var age = getRandomInt(13, 89);
var lastPerson = LinePeople.findOne({}, {fields:{x:1},sort:{x:-1},limit:1,reactive:false});
if (lastPerson) {
console.log(" in lastPerson.. if block");
LinePeople.insert({x:(lastPerson.x + 1), y:age});
} else {
console.log(" in lastPerson.. else block");
LinePeople.insert({x:1, y:age});
}
},
'click #removeDataButton': function() {
console.log(" in line removeButton");
var lastPerson = LinePeople.findOne({}, {fields:{x:1},sort:{x:-1},limit:1,reactive:false});
if (lastPerson) {
LinePeople.remove(lastPerson._id);
}
}
});
}
if (Meteor.isServer) {
console.log("in line Server");
}

While following the Getting Started tutorial on the official meteor.js website I've had the same problem with autopublish turned on.
Turned out the issue was I created my Tasks collection inside the imports/ folder. Thus it was not implicitly imported on the server.
I had to explicitly import it on the server to solve the issue.
server/main.js
import { Meteor } from 'meteor/meteor';
import '../imports/api/tasks.js';
Meteor.startup(() => {
// code to run on server at startup
});
As you can see the import is not used by my code but is required anyways.

Thanks for the help... I actually got it worked by publishing the collection and giving it some permissions:
This code is placed in "myapp/shared/collections.js". (Placed them separately to handle all the other collections which I would add for other graphs)
lineVar = new Meteor.Collection("linenvd3");
lineVar.allow({
insert: function () {
return true;
},
update: function () {
return true;
},
remove: function () {
return true;
}
});
This code is placed in "myapp/server/publish.js"
Meteor.publish('line', function () {
return lineVar.find();
});
Then, this is modified Javascript made look more simpler and comprehensive.
if (Meteor.isClient) {
Meteor.subscribe('line');
Template.linenvd3.rendered = function() {
var chart = nv.models.lineChart()
.margin({left: 80})
.useInteractiveGuideline(true)
.transitionDuration(350)
.showLegend(true)
.showYAxis(true) //Show the y-axis
.showXAxis(true) //Show the x-axis
;
nv.addGraph(function() {
chart.xAxis.axisLabel('Person number').tickFormat(d3.format('d'));
chart.yAxis.axisLabel('Age (years)').tickFormat(d3.format('d'));
d3.select('#lineChart svg').datum(
[{ values: lineVar.find().fetch(), key: 'Age' }]
).call(chart);
nv.utils.windowResize(function() { chart.update() });
return chart;
});
Deps.autorun(function () {
d3.select('#lineChart svg').datum(
[{ values: lineVar.find().fetch(), key: 'Age' }]).call(chart);
chart.update();
});
};
}
