Describe the bug

Trying to scan a Crates.io packages results in an error in Dejacode.

Product inventory. Tried to scan 2 that failed. 2 not yet scanned.

In the logs:

[dejacode_web]                       | INFO "GET /packages/nexB/9bf0a93b-7689-4439-bcb9-116fb8e02df7/tab_purldb/ HTTP/1.1" 200 1691

Trying to manually access http://localhost:8000/packages/nexB/pkg:cargo/allocator-api2@0.2.21/9bf0a93b-7689-4439-bcb9-116fb8e02df7/#scan shows:

The error shows:

Error: The URL https://crates.io/api/v1/crates/allocator-api2/0.2.21/download is not reachable.

However, it works from the browser.

Trying with Curl:

$ curl  https://crates.io/api/v1/crates/allocator-api2/0.2.21/download
{"errors":[{"detail":"We are unable to process your request at this time. This usually means that you are in violation of our API data access policy (https://crates.io/data-access). Please email help@crates.io and provide the request id ada0085e-e429-4053-fc90-a8bc90cf6dcc"}]}

This seems to indicate that it is some rate limiting.

To Reproduce
Steps to reproduce the behavior:

1. Go to DejaCode
2. Import an SBOM with Rust dependencies from crates.io in it
3. Trigger a scan on the Rust dependencies from crates.io
4. See the error in the inventory page.
5. Considering going to the page of the package to see the specific error page of the package to be scanned.

Expected behavior

• To have DejaCode actually be able to download the Crates.io files.
• Otherwise have a more explicit error that helps the user to conclude what is the underlying issue.
