could not create request: %w

Error message

could not create request: %w

What it means

Wraps an error from http.NewRequestWithContext inside the Hyper provider client's doGet (used by Get to fetch /api/v1/provider). The method, URL composition, and body are all static, so a failure here means the composed URL (r.baseURL + path) is not a valid URL. The etag and auth headers are set only after this point.

Solutions

1. Verify the Hyper base URL configuration (default https://api.hyperbolic.xyz) is set and well-formed.
2. If the base URL comes from an env variable or config field, print it and correct it.
3. Re-copy the Hyper API endpoint from their docs, ensuring https:// scheme and no trailing spaces.
4. Check that no custom override in crushrc is clobbering the default with an invalid value.

Example fix

// before
baseURL := "" // unset -> invalid composed URL
// after
baseURL := "https://api.hyperbolic.xyz"
// composed: https://api.hyperbolic.xyz/api/v1/provider

u, err := url.Parse(hyperBaseURL + "/api/v1/provider")
if err != nil || u.Host == "" {
    return fmt.Errorf("hyper baseURL %q produces invalid request URL", hyperBaseURL)
}

func validHyperBase(raw string) bool {
    u, err := url.Parse(strings.TrimSpace(raw) + "/api/v1/provider")
    return err == nil && (u.Scheme == "http" || u.Scheme == "https") && u.Host != ""
}

result, err := client.Get(ctx)
if err != nil {
    if strings.Contains(err.Error(), "could not create request") {
        log.Fatalf("check hyper base URL configuration: %v", err)
    }
    return err
}

When it happens

Trigger: Calling hyper client Get when r.baseURL is empty, malformed (bad scheme, control characters, spaces), or was misconfigured so the concatenation baseURL+"/api/v1/provider" fails to parse.

Common situations: Hyper base URL left empty because configuration did not resolve; a custom override with a typo like "hyper:/api" or trailing whitespace; env expansion producing a garbage value for the base URL.
