[quarkres] create request failed

Error message

[quarkres] create request failed: %w

What it means

QuarkResPlugin.doSearch builds a GET request to apiBase+escaped keyword; if http.NewRequest fails it returns "[quarkres] create request failed" wrapping the cause. Given the URL is constructed from a constant base plus url.QueryEscape(keyword), failure indicates malformed URL text — usually control characters in the keyword or a broken apiBase constant.

Solutions

  1. Strip control characters/newlines from the keyword before building the URL.
  2. Confirm apiBase has a valid scheme and no whitespace.
  3. Log searchURL on failure and run url.Parse on it to see the exact problem.
  4. Check the wrapped %w error for the precise parse failure.

Example fix

// before
searchURL := apiBase + url.QueryEscape(keyword)
req, err := http.NewRequest("GET", searchURL, nil)
// after
keyword = strings.TrimSpace(strings.Map(func(r rune) rune {
    if r < 32 || r == 127 { return -1 }
    return r
}, keyword))
searchURL := apiBase + url.QueryEscape(keyword)
req, err := http.NewRequest("GET", searchURL, nil)
if err != nil {
    return nil, fmt.Errorf("[quarkres] create request failed: %w", err)
}
Defensive patterns

Strategy: validation

Validate before calling

u, err := url.Parse(searchURL)
if err != nil || (u.Scheme != "http" && u.Scheme != "https") {
    return fmt.Errorf("cannot build search request for %q", searchURL)
}

Try / catch

results, err := p.doSearch(client, keyword, ext)
if err != nil {
    if strings.Contains(err.Error(), "create request failed") {
        // sanitize keyword / fix apiBase, then retry
    }
}

Prevention

When it happens

Trigger: http.NewRequest errors because searchURL fails url.Parse — e.g. keyword containing raw newlines/control bytes that survive QueryEscape, or apiBase misconfigured without a valid scheme.

Common situations: User input passed through with embedded newlines (multi-line paste); apiBase edited with a typo (missing https://, stray spaces); plugin source modified with an invalid base URL.

Understand the failure class

Background: "Invalid URL" / "URL cannot be empty": fix the malformed or missing URL behind request-construction failures — this error's family across 50 libraries.
