In the end of the lesson I get the error from Heroku

java.io.FileNotFoundException: https://taskie-rw.herokuapp.com/api/register

#3

Hey there!

Are you sure you’re using POST and not GET? I just tested the request, and everything is working fine!

#4

I found the problem. I missed a quote in the end and incorrect data causes HTTP 400 that interpreted as FileNotFoundException for some reason. Don’t know why but now it works for me.

#5

The service doesn’t work for me either, I even tried it for postman. I get error 400, and when I debug I get FileNotFoundException

Hey @ricindigus!

Have you checked that your JSON string is valid? We’ve had issues where people missed a quote at the end, or didn’t format something correctly!

Also, make sure that you’re using POST for register, instead of GET. I just tested out the API using Postman, and it seems to be working fine.

So url should be: “https://taskie-rw.herokuapp.com/api/register” and the JSON should look like this (if you use an online formatter):

{
	"name":"username",
	"email":"email@email.com",
	"password":"password"
}

Thanks!

Hi! I have a problem with the registration of an user, i got “Invalid data!” every time. I even tried to run your code from Final folder and I get the same error
 so i don’t think it’s an internal problem :-?

Hey @moonlime!

Have you tried using different data for the user? Given that I’ve used the data in the video, it won’t make sense to reuse that data because such a user is already registered. But if you try to use different data, you should be fine. Try changing the email to something unique and it should work fine!

#11

I used your code, not your credentials
 tried different combinations of users/emails/passwords
nothing works

#12

I just tested the API using Postman and everything works.

Have you set the appropriate flags on the HTTP connection: “doInput” & “doOutput” to true?

Did you check your JSON structure & formatting to be correct/as in the tutorial? All the escaped String literals, all the colons and commas?

This should be your JSON structure:

{
	"name":"pilips",
	"email":"example@mail.com",
	"password":"password"
}

Edit: I’ll check everything with the project too, but last time I checked this it worked fine.

Edit 2: I just downloaded the final project of E4, and everything worked for me. Created an account without a problem.

#13

I’ve created a new device and run it again but on API 30, so i guess that was the problem:-? Thank you for your time tho

is the Base_url still valid? Currently doing the tutorial but it doesn’t seem to be ‘live’ anymore as I get ‘Invalid Data’ when trying to register in the app and when I go to the link i get:
Cannot GET /api/register

Hey @swiftlearnerlv !

The app is still running. You should be using POST for registering if I’m not mistaken, as per other comments above! Also - the reason you might receive invalid data is because your JSON is not formatted correctly, so please check that too.

As for the emails not being valid etc, that’s because the email is already registered and you can’t register with the same email twice. You should use your email or a dummy email from a temp account to register to the app.

Thanks!
