Web Application is throwing 500 server error code due to One Agent installed on web server

[Adi_10]

Hi Team,

Need help my web server, where my url is hosted throwing this error - 500 issue, after tracing logs i came to know that: 

7-Feb-2025 20:36:32.552 SEVERE [main] org.apache.tomcat.util.descriptor.web.SecurityConstraint.findUncoveredHttpMethods For security constraints with URL pattern [/*] only the HTTP methods [TRACE HEAD DELETE CONNECT OPTIONS PUT] are covered. All other methods are uncovered.

    at com.dynatrace.agent.introspection.uem.impl.AutoHtmlInjectorWriter.write(AutoHtmlInjectorWriter.java:69)

However I have stopped one Agent service then my url is up again,

Can you help how do i sort this out ?

This is really a support case, however, I have previously seen this occurring where there is a double injection of RUM occurring between the App Services and Web Services.

The solution we had was to disable the RUM injection on the service / process and let the Web Server do the RUM injection. 

Hope this helps.
