Parley | browser plugin that provides a more private , secure | Notification library

I recently updated Sails from 0.12 to 1.0.2 on my laptop and started a new project. I'm trying to connect to a MongoDB database using sails-mongo but I get the following error:

I created an simple Sails.JS test app

Recently I wrote for myself a demo-app (full code: https://github.com/aversilov/parley-fork) based on this Ahamed Foysal's example (https://www.codementor.io/foysalit/rest-api-with-mongodb-and-nest-js-hto6x5120). As you know NestJS is a very young framework and there are catastrophicaly small number of tutorials & demo-apps for learn it. So, I create all files in the project, run mongod in separate terminal window, and run app: npm run start But the app is crashed with:

Error output

P.S. I checked - circular references in my codebase don't exists (Vue + typescript - TypeError: Object prototype may only be an Object or null: undefined).

Any help would be greatly appreciated.

I am testing how to change text and CSS elements using Javascript

I have three buttons in my HTML, only one so far that I am using (Change Title). I would like to change the H1 Text when I click the button.

Using my current coding, when I click the button nothing happens and I get the following displayed in the web developer tools console:

*ReferenceError: changeTitle is not defined [Learn More] Index.html:1:1

Onclick file:///D:/Google%20Drive/Programming/EDX/Introduction%20to%20JavaScript/Module_1/index.html:1:1*

Questions:

1. Can someone please help me understand why the browser says that the changeTitle function is not defined when I believe I have defined it in the external JS file.
2. Am I able to use the onclick method?? in the tag element so that I do not have to use buttons?

Please find snippet below:

I cannot figure out how to make two separate legends for my geom_point and my geom_line data. Currently, I have a legend describing what the different linetypes mean, but when I try to add a legend to describe what the different point shapes mean (blue triangles and circles), blue circles simply overlap the linetype legend. Many thanks to anyone who can help me make two separate legends for linetype and point shape. Below is my code, my data, and a picture of my current graph:

Here's my data, called "Data":
