If it's not necessary, I'd suggest to remove the HTTPS redirection from the ASP.NET Core sample:

https://github.com/Autodesk-Forge/learn.forge.viewmodels/blob/netcore/Startup.cs#L28

It can cause issues with certificates. For example, on my macOS the server app would always redirect me from localhost:5000 (HTTP) to localhost:5001 (HTTPS) but the certificate wasn't working and had to be worked around: https://www.c-sharpcorner.com/article/how-to-enforce-htts-development-certificate-for-asp-net-core/.

And after resolving the certificate problem, there are CORS issues as well:

Access to XMLHttpRequest at 'https://localhost:5001/api/forge/oss/buckets?id=%23' (redirected from 'http://localhost:5000/api/forge/oss/buckets?id=%23') from origin 'http://localhost:5000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I used visual studio 2015 and I am receiving the error:

Failed to load resource: the server responded with a status of 404 (Not Found) ForgeViewer.js:20 Uncaught TypeError: Cannot read property 'search' of null at onDocumentLoadSuccess (ForgeViewer.js:20) at b.ViewingApplication.<anonymous> (viewer3D.js:151999) at f (viewer3D.js:139004) at XMLHttpRequest.m (viewer3D.js:74916)
on the web console. How do I resole the error so that I can see my 3d model on the viewe

I cannot find the .env.example file

I am using Node v10.17.0. When I first load the page "localhost:3000", I see continuously "Loading ..." in the tree (see attached screenshot) without being able to add new buckets.

In the terminal, I see the followings errors/warnings:
(node:14964) UnhandledPromiseRejectionWarning: Error: connect ECONNREFUSED 3.233.190.64:443

Could it be related to node version? I did npm install.

Thanks

It seems the following code at https://github.com/Autodesk-Forge/learn.forge.viewmodels/blob/php/server/config.php#L14 to get env is not working any more, need to update with latest change.

// load the environment variable from .env into your application
$dotenv = Dotenv::create(DIR);
$dotenv->load();
$forge_id = getenv('FORGE_CLIENT_ID');

Hi

Did everything in the tutorial. Everything else gave an error.

`<?php
namespace Autodesk\ForgeServices;
use Dotenv\Dotenv;

class ForgeConfig{
private static $forge_id = null;
private static $forge_secret = null;
public static $prepend_bucketkey = true; //toggle client ID prefix to avoid conflict with existing buckets

public static function getForgeID(){
  $forge_id = '';
  if(!array_key_exists('FORGE_CLIENT_ID', $_ENV)){
    // load the environment variable from .env into your application
    $dotenv = Dotenv::create(__DIR__);
    $dotenv->load();
  }
  $forge_id = $_ENV['FORGE_CLIENT_ID'];
  return $forge_id;
}

public static function getForgeSecret(){
  $forge_secret = '';
  if(!array_key_exists('FORGE_CLIENT_SECRET', $_ENV)){
    // load the environment variable from .env into your application
    $dotenv = Dotenv::create(__DIR__);
    $dotenv->load();
  }
  $forge_secret = $_ENV['FORGE_CLIENT_SECRET'];
  return $forge_secret;
}

// Required scopes for your application on server-side
public static function getScopeInternal(){
  return ['bucket:create', 'bucket:read', 'data:read', 'data:create', 'data:write'];
}

// Required scope of the token sent to the client
public static function getScopePublic(){
  // Will update the scope to viewables:read when #13 of autodesk/forge-client is fixed
  return ['data:read'];
}

}
`
Dotenv:create like suggested in the tutorial here on GitHub gives 404 error localhost page can't be found. Is there something else here that we are missing?

Add a GitHub button / logo on homepage... please.

Keep the web free - wahooo !

Although elegant, the setTimeout fails if the machine hibernate (which happens on localhost), after that the access_token does not refresh and we need to restart the project.

Hi,
I'm trying to make this tutorial (php) and i'm getting blank page with HTTP Error 404, any idea ?
nothing in debugger, nothing enywhere else...
When calling this uri http://localhost:3000/api/forge/oss/buckets i get this error

It is possible to create a bucket with no name.

This is happening in the node.js demo

Couldn't see my BIM360 files/folders because there were no instructions on how to add Forge Client ID into the BIM360 Admin page...

like this one...
https://bim360xls.autodesk.io/# -> click Config button -> step by step instructions

Thank you

The client side code for file uploading (https://github.com/Autodesk-Forge/learn.forge.viewmodels/blob/nodejs/public/js/ForgeTree.js#L143) is adding a new change event handler every time the user uses the "Upload File" action. So, for example, when the user is uploading a 5th file without reloading the page, the change event handler (and a post request to the server) is actually triggered 5 times.

I can log in using the 3 legged authentication but once I accept the permissions then I get this error.

Error calling Gettoken: The underlying connection was closed: An unexpected error occurred on a send.

Can't clone using the link. When I clone using the url there are a lot of files missing.

The instructions in README say
git clone https://github.com/autodesk-forge/forge.learning.viewmodels
perhaps they should say
git clone https://github.com/Autodesk-Forge/learn.forge.viewmodels.git
?

while creating a new bucket like "zaferbucket" i'm getting an internal server error (500)

ExceptionMessage: "Error calling CreateBucket: {"reason":"Valid field 'bucketKey' must be of the form [-_.a-z0-9]{3,128}"}"

I've noticed this in the nodejs branch, but other branches/languages are probably affected, too. When getting objects of a specific bucket, the forge-apis only return 10 items by default. The code should either set a higher limit, or better, collect the objects in a loop.

upper/lower case and special chars

It looks like this line of code could cause problems:

https://github.com/Autodesk-Forge/learn.forge.viewmodels/blob/net/forgesample/Controllers/OSSController.cs#L61

Because according to https://github.com/Autodesk-Forge/forge-api-dotnet-client/blob/master/docs/ObjectsApi.md#parameters-6 the (missing) limit parameter defaults to 10.

When I attempt to open the web application, the buckets and objects tab loads forever. In addition, it will not allow me to create a bucket or upload a file for the viewer. I have tried it using PHP, node.js, and Java. Please help, thank you
