Why does a GET request to retrieve the current locale for a user result in error 500?

From my Connect plugin I call /rest/api/2/mypreferences/locale to retrieve the locale currently set for my user. This results in a error 500 (Internal server error).

This is the corresponding log:

    at org.springframework.web.client.DefaultResponseErrorHandler.handleError(DefaultResponseErrorHandler.java:81) ~[spring-web-4.3.12.RELEASE.jar:4.3.12.RELEASE]

And this is the code:

private static final Logger LOG = LoggerFactory.getLogger(JiraHelper.class);

private static final String JIRA_REST_BASE_PATH = "/rest/api/2/";

private static <T> T getJiraValue(RestTemplate template, String baseUrl, String restPath, Class<T> type) {
    String url = baseUrl + JIRA_REST_BASE_PATH + restPath;
    LOG.info("GET from URL: {}", url);
    ResponseEntity<T> result = template.getForEntity(url, type);
    LOG.info("Response status = {}", result.getStatusCode().toString());
    return result.getBody();
}

public static Locale getCurrentLocale(RestTemplate template, String baseUrl) {
    String jiraLocale = getJiraValue(template, baseUrl, "mypreferences/locale", String.class);
    LOG.info("Jira user locale is: {}", jiraLocale);
    Locale locale = new Locale(jiraLocale);
    return locale;
}

Locale locale = JiraHelper.getCurrentLocale(atlassianHostRestClients.authenticatedAsHostActor(), hostBaseUrl);

If I try the same URL in my browser while being authenticated in another tab, I get the correct locale.

And the getJiraValue() method is working fine when looking up issue types via the issuetype REST URL.

Any ideas what’s wrong with the code?

Hi, @matthias1.

Checking the REST API docs for Get locale, it says that

Apps cannot access this REST resource.

which means that there is nothing wrong with your code and this is the expected behavior. You can try Get current user, it also returns the locale for you.

Best regards,
Ian

Hi @iragudo,

sorry I didn’t realize that. Now it’s working fine.

Thanks a lot,
Matthias

Glad we could help :slight_smile:
