Failed to load metadata Error

Hi All,
Due to security reasons some versions of Tomcat like 8.0 and 8.5 does not allow some characters like ‘[’ or ‘]’. The solution for this is just to allow these characters “relaxedQueryChars=”[,]“” in server.xml file in conf folder as below

<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" relaxedQueryChars="[,]"/>
