The error occurs when the customer, using a trial license for MPS and NDR, clicks on the Malware Prevention tab. 

Environment

NAPP 4.2 and earlier
NSX 4.2.1 and earlier
Browser/Platform: Any

Cause

The error NG0701 is caused by a conflict related to unsupported locale settings in the UI. This issue has been found in multiple places. When an unsupported locale setting is used, the UI fails to load properly, leading to an error. The currently supported locales are en-US, de-DE, es-ES, fr-FR, ja-JP, ko-KR, zh-CN, zh-TW, and it-IT. All other locales are not fully supported.

In this case, the customer locale seems to be set to da-DK, causing the Malware Prevention UI (and other sections like the Upgrade UI, NSX Intelligence UI, etc.) to fail to display properly. This crash could occur in various places; in this instance, it caused a failure in the DatePipe, a native Angular library, resulting in an NG0701 error. This issue is more noticeable in environments using trial licenses, but it can also occur in other situations if the locale is set improperly.

Resolution

The fix will be merged in a future release. 

 

Workaround :


The workaround is to change the locale to any supported locale, such as en_US.

Follow these steps to change the locale:

Navigate to the system locale settings.
Set the locale to en_US or another supported locale.
Reload the UI to ensure the changes take effect and confirm that the issue is resolved.
