Topic solved

Dear all,

We are facing problems with the cloud target API for a couple of hours now. No changes on our end.

Error: HTTP 400 on CRUD operations.

Any changes we have to be aware of? Anyone facing the same problems?

Cheers

Hello all

We have the same issue on our end also.

400 Bad Request

https://vws.vuforia.com/duplicates/{target_id}

Hey there,

 

Could anyone provide me the transaction_id? This should be attached to the response you're getting.

Thanks.

 

Kind regards,

Hi, I have problems too. I can't upload files to the cloud.

This is an *Urgent* issue for our AR app in production.

Our social AR app is built around Vuforia Cloud features and it is almost completely unusable at the moment, with users already bringing up the issues.

We are considering putting our app into maintenance mode to prevent users logging into the app while this issue persists. It's a nuclear option, but preferable to getting 1-star app reviews.

Can we please get an ETA on a fix?

 

Details:

- Uploading image targets to VWS cloud database results in "400 Bad Request" response.

- Unable to retrieve transaction_id, the only response text we are getting is "Bad request".

- We are using Unity 2019.3, Vuforia engine v9.3.3, VWS Cloud license (only used about 11k cloud targets out of 100k so still within limits)

-To check that the issue didn't spawned from anything we have changed, we re-tested cloud upload in our older builds, going as far as 4 months old, and they also fail to upload to cloud now.

 

@Patrick if you need further info or testing, please reach out.

Hey there,

 

Thanks for the detailed information. I know that our R&D has been looking for the issue since Friday. I've raised the problem and currently there's a round of high-priority investigation internally for the issue. I will check if there's an update and hopefully provide some feedback as soon as possible. 

I will also be reaching out directly via email to everyone in this thread to gather more details. 

For future cloud support, you're also able to create a cloud ticket via the production support as cloud developer. This is much faster than the forums: https://developer.vuforia.com/support/contact/cloud

Please note that the support form is only available with a paid plan.

 

Kind regards,

Hey all,

 

The issue you’ve encountered seems to be an unintended side effect of the new internal cloud deployment made on Thursday (20-01-2022) by our R&D. You might run into this issue if you encountering one of these errors:

  • Error: HTTP 400 on CRUD operations.
  • 400 Bad Request

We concluded that only 0.084% of all failed requests were affected since the change by this problem.

There are three possibilities that can cause the failure in your requests:

  • using non upper-case methods: “Get” instead of “GET”, or “post” instead of “POST”, etc.
  • using leading or trailing spaces around the method
  • missing or malformed Host header

To solve the first two issue you must make sure that you’re using valid methods. Down below you can find examples of valid and invalid methods:

 

Examples of valid methods Examples of invalid methods
GET Get
POST get
DELETE PosT
  `  GET` (leading spaces)
  `GET  ` (trailing spaces)

 

The latter can be solved by making sure that the Host: vws.vuforia.com header is present in the HTTP request.

I am sorry you were affected by the changes. I provided the same feedback to NRLN & Bernd173 via email.

 

Kind regards,

Thanks Patrick for reaching out to help!

We have fixed this issue from our end.

Just in case other Unity developers came across this issue, we rewrote our code to use "HTTPRequest" class instead of the ancient "WWW" class and that seemed to have do the trick.

how do we change from www to HTTPRequest?

I still can't upload photos to the cloud of vuforia.

I have these lines:

WWWForm form = new WWWForm();

WWW request = new WWW(serviceURI,System.Text.Encoding.UTF8.GetBytes(JsonUtility.ToJson(model)),headers);

yield return request;

 

how can I solve that?
