HI Everyone, I’m using a https outcalls feature of icp canisters to compose a project which fetchs data from external rest api and store it in the canister storage.  
Here’s the code I used to fetch data.

```rust
match ic_cdk::api::management_canister::http_request::http_request(
    ic_cdk::api::management_canister::http_request::CanisterHttpRequestArgument {
        url: format!("{}&timestamp={}", source_url, get_time_in_milliseconds()),
        max_response_bytes: Some(1024 * 10),
        method: ic_cdk::api::management_canister::http_request::HttpMethod::GET,
        headers: Vec::new(),
        body: None,
        transform: None,
    },
    500_000_000,
)
.await
{
    Ok((response,)) => todo!(),
    Err((code, err)) => {
        ic_cdk::println!("Error code {:?}:\n{}", code, err.clone());
        todo!()
    }
}

```

I verified that the target url is returning an expected value when hit by using curl command.  
However, after deploy this code, I got the following error logs from the canister.

```auto
[313347. 2025-01-27T09:50:15.93760109Z]: Error code SysTransient:

```

Can you help me to troubleshoot this issue, please?

According the shared code snippet, this question appears to be a duplicate, if I’m not wrong, of what we discussed on Discord earlier today. So for tracability, we have enumated few ideas of solutions there.
