Error message

assemble requestUrl error:

What it means

assembleAuthURL builds a percent-encoded query string from request parameters using URLEncoder. If encoding any key/value throws (e.g. an unsupported charset name at runtime), the lambda wraps it in a RuntimeException with the message 'assemble requestUrl error:'. It is a defensive catch-all; under normal UTF-8 setup it should never fire.

Solutions

1. Verify the JVM supports the UTF-8 charset (standard JVMs do; a custom/minimal JRE may not)
2. Prefer the overload URLEncoder.encode(value, StandardCharsets.UTF_8) (Java 10+) so no charset-name lookup happens
3. Improve the wrapper to preserve the cause: new RuntimeException(e) instead of only e.getMessage()
4. Log the offending key/value type to pinpoint which entry failed encoding

Example fix

// before
URLEncoder.encode(entry.getKey(), String.valueOf(StandardCharsets.UTF_8))
// after
URLEncoder.encode(entry.getKey(), StandardCharsets.UTF_8)

if (params == null || params.isEmpty()) throw new IllegalArgumentException("auth params required");

try { String url = AuthStringUtil.assembleAuthURL(baseUrl, params); } catch (RuntimeException e) { log.error("auth URL assembly failed: {}", e.getMessage(), e); throw new ServiceException("Unable to build auth URL"); }

When it happens

Trigger: Calling AuthStringUtil.assembleAuthURL with a parameter map whose key or value fails URLEncoder.encode — practically only when String.valueOf(StandardCharsets.UTF_8) cannot resolve to a supported charset in a stripped/restricted JVM environment.

Common situations: Running on a minimal JRE without the UTF-8 charset provider; exotic custom security policies blocking charset lookup; repackaging the utility into an environment with a broken java.nio.charset setup.

Understand the failure class

Background: "Invalid URL" errors: why new URL(), URI.parse, and reqwest::Url reject your string — missing scheme, whitespace, and bad path format — this error's family across 39 libraries.
