Runtime Error - Uncaught (in promise): [object Object]

Question

I'm using this example to understand the operation between ionic and php with mysql But I find that this error appears to me and I do not understand where it comes from. The strange thing is that when I load a note it works and it is loaded into the database.

He left the repository in case they want to visualize the code https://github.com/javazika/ionic_crud_php_msqyl

Console

Does the console show anything else? Can you show us the code you were working? — Script47, Dec 05 '18 at 13:16
That is how you are supposed to test your application on desktop. The typescript needs to compile and `ionic serve` compiles it. — Script47, Dec 05 '18 at 13:32
@deceze although that is an error in the console, it isn't the cause of OP's error. — Script47, Dec 05 '18 at 13:33
@Script47 What is then? The request fails, the associated promise rejects, the rejection is uncaught. — deceze, Dec 05 '18 at 13:39
@Script47 So ... when I want to test the application, do I have to test it based on what I compiled? When I try it from the compiled if it is working. I do not understand why it does not work directly when running from "ionic serve" What is different? — Matias Angeluk, Dec 05 '18 at 13:43
@deceze From your dupe, would the OP find the answer of running `ionic serve`? — Script47, Dec 05 '18 at 13:43

You need to run the ionic serve command through CMD / Terminal while in your project directory.

This transpiles your TypeScript and builds your app to make it runnable on your device, as per the description from the documentation:

Start a local dev server for app dev/testing

Easily spin up a development server which launches in your browser. It watches for changes in your source files and automatically reloads with the updated build.

It has live-reload capabilities built into it so you can edit the code on-the-fly and see those changes, once you make a change, look in the console, it should say rebuilding / compiling. That is the TypeScript being transpiled (again) to JavaScript.

Once you run the command it'll open up a port on localhost and automatically open your app in the browser.

Thank you! I already understand a little better the functioning of ionic. and thanks add @deceze `` and the console error disappears — Matias Angeluk, Dec 05 '18 at 13:54
