I'm just trying to get a DOT diagram to render. I have followed the documentation (https://github.com/magjac/d3-graphviz) to add the package and use it but when I try to run the application and access the DOT diagram, nothing renders and the the following error is thrown:

ERROR TypeError: Cannot read property '__graphviz__' of null. console error message

The app is an Angular 12 project here is the dependency list that is used

I have upgraded my angular to angular 13. when I run to build SSR it gives me following error.

I was using ang-jsoneditor before I upgrade my nodejs (was 8, now 12) and angular (was 7, now 10). After the upgrade, the ang-jsoneditor seems not working, and error is

I've got this somewhat old Angular web application which was updated from Angular 6 to Angular 12, however, Angular CLI is not being used for building it, instead it relies on Webpack 5, its loaders and AngularWebpackPlugin from @ngtools/webpack.

Recently, I needed to upgrade to a latest version of a library I was using and I got greeted with the following warning after my production build:

I am using MatSelect, MatChips and many other Mat libraries but none seem to work with AOT mode enabled. Dropdowns, MatChip inputs are not responding after clicks. They are working without AOT. Below is my package.json file and code snippet for MatSelect. I have imported MatSelectModule and all other required Material modules. Not able to get what am I missing here. Please help.

P.S. I tried removing [(ngModel)] and setting it in the ts file but it still doesn't work.

I received a hot potato of an Angular 4.4 application which is quite fragile. When I try to update the auth0-js module the app stops loading and its bootstrap component constructor is never called. It loads the initial html, runs app.module.ts and main.ts. Then it appears to just stop. I've gone through debugging, single-stepping, several times in Chrome & FF developer tools. It just seems to stop. I've put all sorts of console.log statements at loading and constructors of various components and modules. It apparently never calls the constructor of app.component.ts.

I have carefully isolated the changes to required modules from the auth0-js module. There is only one required module, qs, which is also used by my code or any other js modules. The other required modules are only used by auth0-js. I froze the top level qs version and forced npm to install that as a dependency of auth0-js when upgrading. I can find no changes that could cause this breakage.

And, as far as the auth0-js library itself, I have already made use of the latest version in another similar project. And, the code executed before the app just stops does not include any calls to auth0-js. In other words, that code is not touched before the app stops running.

Building is done with the Angular CLI version 1.7.4, installed local to the project (in ./node_modules/). Then it is built/launched via ng serve --env local. That server seems a black box with no useful logging. I switched to serving via nginx and building via ng build --output-hashing=all --env local. Still not getting any further. Its been several weeks and my forehead is becoming concave. Any and all suggestions are more than welcome.

Here is my main.ts

I'm trying to make a call to a service and build an object with the resulting value. If I knew what I was doing, I'd also handle errors, but I don't know how. Unfortunately, the code begins the service call, then returns to the statement following the service before the service call finishes.

I don't care how un-modern, un-cool or whatever it is, I want this code to wait for the service to succeed or fail. Everything I do in the app depends on this service succeeding anyway.

I both tried setting breakpoints and as adding logging statements.
