Download file with square brackets in the name through CMIS does not work

Hello,

Example filename: "Picture of a bird 4{2}123 (ID 1).png".

We can upload the file with dotCMIS okay, but can not download it later.

A 400 bad request is gotten from server with following response:

Message: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986

Exception: 

java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986

Is this a configuration issue or a bug in ECM? 

We have Community 6.1.2 running on the server, but no label found for 6.1.x.

Hi,

ACS 6.1 uses Tomcat 8.5+. You may need to add these characters to Tomcat config => https://tomcat.apache.org/tomcat-8.5-doc/config/http.html - relaxedPathChars &/or relaxedQueryChars settings.

See this Stack discussion of the topic and your options.

HTH,
