Error parsing URL: {message}
Error message
Error parsing URL: {message} What it means
Thrown by ElasticConnection.executeRawStatement when constructing the request URL (hostURL + path) raises a URISyntaxException. The hostURL or the appended path is not a valid URI reference, so new URI(...).toURL() fails before any network call. This is a client-side configuration/input error, not a server error.

Solutions
- Fix hostURL to be a well-formed absolute URL (scheme + host [+ port]), no spaces.
- Percent-encode any special characters in the path segment before passing it.
- Validate hostURL + path with new URI(...).parseServerAuthority() before calling executeRawStatement.
- Strip stray whitespace from configuration values.
Example fix
// before
conn.executeRawStatement("GET", "bad path with spaces", body);
// after
String path = URLEncoder.encode("bad path with spaces", StandardCharsets.UTF_8);
conn.executeRawStatement("GET", path, body); Defensive patterns
Strategy: validation
Validate before calling
String combined = hostURL + path;
try { new URI(combined).toURL(); }
catch (URISyntaxException e) { throw new IllegalArgumentException("bad URL: " + combined, e); }
conn.executeRawStatement(command, path, body); Type guard
boolean isValidRequestUrl(String hostURL, String path) {
try { new URI(hostURL + path).toURL(); return true; }
catch (Exception e) { return false; }
} Try / catch
try {
conn.executeRawStatement(command, path, body);
} catch (ElasticException e) {
if (e.getMessage().startsWith("Error parsing URL")) {
path = URLEncoder.encode(path, StandardCharsets.UTF_8);
conn.executeRawStatement(command, path, body);
} else throw e;
} Prevention
- Keep hostURL a well-formed absolute URL with no spaces.
- Percent-encode special characters in path segments.
- Validate the combined URI parses before issuing requests.
When it happens
Trigger: executeRawStatement with a hostURL or path containing illegal URI characters (spaces, unencoded special chars, bad scheme). new URI(hostURL + path).toURL() throws URISyntaxException, caught and rewrapped as ElasticException.
Common situations: hostURL configured with spaces or missing scheme; path argument containing raw query characters that are not percent-encoded; a trailing/leading slash mismatch producing an invalid reference; copy-paste error in the BSim server URL setting.
