Problem accessing the stored queries in the saved query folder

Products

• CA Service Desk Manager

Issue/Introduction

You created and saved a custom query, but accessing it returned an "HTTP Status 400 - Bad Request" error, referencing "The valid characters are defined in RFC 7230 and RFC 3986". However, the query worked correctly after associating it with a list via the Queue Manager. Replacing "list_in.htmpl" with a non-customized version didn't fix the problem.

Environment

Release: 17.4 +

Components: CASM - Tomcat

Cause

The presence of special characters such as [ ] &#... embedded in the HTTP request header causing "Bad Request" error in tomcat.

Resolution

Add the following to the HTTP and HTTPS connector tags in server.xml file as outlined in the technical documentation linked here: Invalid character is found in the request target

relaxedPathChars="[]|{}^\`"<>" relaxedQueryChars="[]|{}^\`"<>"

Example:  The out of box Connector tag for regular HTTP in server.xml will read as:

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

Modified, it will read as:

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" relaxedPathChars="[]|{}^&#x5c;&#x60;&quot;&lt;&gt;" relaxedQueryChars="[]|{}^&#x5c;&#x60;&quot;&lt;&gt;"/>
