public addContact(inContact: IContact): Promise<IContact> {

I get an error for the add contact worker. Does anybody know what the issue might be?
I take all the steps based on the textbook and source code, but the error still persist.
You can see the error on this screenshot:

same here, even the repo's code produces the same error.

Hi... can you tell me what IDE/editor you're using? I'm not seeing such an error in IntelliJ IDEA.

Also, is the code compiling and running for you from a CLI? For me, it is, and it seems to run just fine.

Hi.. I am using VS Code. Could that be the reason I'm getting an error?

[FarzanKh]

I just tried with IntelliJ IDEA and I got the same error. Screenshots:

Hmm, interesting. I don't really use VSCode myself, but I'm using IDEA too and not seeing the same... I'm sure there's some inspection setting difference or extension or something... but, ultimately it shouldn't matter much if it's building and working from the command line. The projects are definitely set up not for any specific IDE or editor, the expectation is that it's built and run from the command line. There, I'm able to build and run both client and server without problems. Are you able to do the same?

[FarzanKh]

By running from the command line you mean typing the curl commands? When I type curl localhost/mailboxes as an example, I get: https://ibb.co/7JnrsyN

[fzammetti]

No, sorry, I mean doing:

npm build

...in the client directory to build the client, then...

npm develop

...in the server directory to build and start the server. Note that you'll need two separate command prompt windows since both steps monitor for changes after doing the build.

I can try and figure out how to resolve what the IDE is showing you, but I'd like to at least make sure you can build and run the project so at least you aren't stuck first.

It should be one of the node modules that's an issue, I ended up resorting to cloning the original server folder, and that worked just fine.

[FarzanKh]

I tried both commands, but I couldn't run the server.
Can you please take a look at this screenshot:

When I clone the repo, do I need to install all the NPM modules again (node mailer for example)?

[guidefari]

yes, after cloning the repo, cd to the client folder and run npm i. run the same command in the server directory

[FarzanKh]

Okay I ran npm i first in the client directory and then in the server directory. I think it installed all the dependencies.
After that I go to the client dir and type npm build and then in the server dir type npm develop, but nothing happens?
Is it going to launch the browser?
