springboot-customized-webapps always brings up errors

[Bill Barni]

If I ever use a customized webjar with spring security, Camunda always throw the error:

Caused by: javax.servlet.ServletException: Could not read security filter config file '/securityFilterRules.json': no such resource in servlet context.
	at org.camunda.bpm.spring.boot.starter.webapp.filter.ResourceLoadingSecurityFilter.loadFilterRules(ResourceLoadingSecurityFilter.java:45) ~[camunda-bpm-spring-boot-starter-webapp-core-7.18.0.jar:7.18.0]

Or if I try to update to version 7.18 I get:
