Can't download 3D-mesh file using provided link

I use Autodesk's Forge Reality Capture API for photogrammetry. All the process from generating photoscene to uploading receiving the download link works perfect, but at the last step, when I need to download .obj file from AWS S3 bucket, it says that I need some extra credentials for access.

Here is the link that I receive:

Is there an easy way to download that file?

I think that your link is trimmed (perhaps by your application).

I just runned a scene and compared my results with your link and note the difference:

yours:

https://[....]/newscene5.obj.zip?
response-content-disposition=attachment[...]newscene5.obj.zip&
X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&
X-Amz-Security-Token=I[...]2

versus mine:

https://[....]/some_scene_name.obj.zip?
response-content-disposition=attachment[...]some_scene_name.obj.zip&
X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&
X-Amz-Security-Token=I[...]D&
X-Amz-Algorithm=AWS4-HMAC-SHA256&
X-Amz-Credential=ASIA[...]_request&
X-Amz-Date=20200820T193456Z&
X-Amz-SignedHeaders=host&
X-Amz-Expires=86400&X-Amz-Signature=a3[...]f7a

As you can see, you are missing a lot of things.

Check in curl or Postman the same results, to identify why you get the trimmed link.

for example, here is my full Postman result:
