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.

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
