Resolution

How to enable CORS in UIMAPI

Open web.xml file ~\Nimsoft\probes\service\wasp\webapps\uimapi\WEB-INF folder

Add below filter before “Front Door Filter” 

Restart the WASP.

 

<filter>
  <filter-name>CorsFilter</filter-name>
  <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
  <init-param>
    <param-name>cors.allowed.origins</param-name>
    <param-value>*</param-value> <!--  add allowed origins separated by comma eg: http://www.broadcom.net -->
  </init-param>
  <init-param>
    <param-name>cors.allowed.methods</param-name>
    <param-value>GET,POST,HEAD,OPTIONS,PUT</param-value>
  </init-param>
  <init-param>
    <param-name>cors.allowed.headers</param-name>
    <param-value>Content-Type,X-Requested-With,accept,Origin,Access-Control-Request-Method,Access-Control-Request-Headers</param-value>
  </init-param>
  <init-param>
    <param-name>cors.exposed.headers</param-name>
    <param-value>Access-Control-Allow-Origin,Access-Control-Allow-Credentials</param-value>
  </init-param>
  </filter>
<filter-mapping>
  <filter-name>CorsFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

Additional Information

It has been found in UIM 20.4 if the uimapi isn't updated, that having CORS disabled can prevent MCS profiles from being edited.  An "unknown error" is displayed stating to contact support.  By enabling CORS, the issue can be resolved.

Of course, updating uimapi will also resolve the issue.
