/my-accounts URLs giving server error on first hit

[former_member637004]

Hi All,

I'm seeing null pointer exception when I hit the url https://hostname/my-account for the first time after clearing cache. Once reloaded issue is disappeared. Below is the exception.

SEVERE: Servlet.service() for servlet [DispatcherServlet] in context with path [] threw exception [Error while processing internal filterchain. Exception occurred at chain position: 12 of 16.

On further debugging, I understood the issue is due to session attribute DETECTED_UI_EXPERIENCE_LEVEL is null for the first time in DefaultUiExperienceService.java, but from second hit, the value is somehow populating with "DESKTOP" and there will not be any issue.

The same issue has also been reported below by some others.

	@Override
	public UiExperienceLevel getUiExperienceLevel()
	{
		// Lookup the UiExperienceLevel override specified in the current session
		final UiExperienceLevel sessionOverrideUiExperienceLevel = getOverrideUiExperienceLevel();
		if (sessionOverrideUiExperienceLevel != null)
		{
			return sessionOverrideUiExperienceLevel;
		}


		return getDetectedUiExperienceLevel();
	}



	@Override
	public UiExperienceLevel getDetectedUiExperienceLevel()
	{
		return getSessionService().getAttribute(DETECTED_UI_EXPERIENCE_LEVEL);
	}
