I'm getting the following error on CAS 5.3 with AJP:

2019-09-30 11:19:19,411 ERROR [org.apache.coyote.ajp.AjpProcessor] Header message of length [11,006] received but the packetSize is only [8,192]
2019-09-30 11:19:19,411 ERROR [org.apache.coyote.ajp.AjpProcessor] Error processing request
java.lang.NullPointerException: null

So I should increase the packetSize of the AJP connector, but it's missing from https://apereo.github.io/cas/5.3.x/installation/Configuration-Properties.html#ajp

Is it hidden somewhere else ?

Hi,

This is written in the doc but not directly, you have the property
cas.server.ajp.attributes.attributeName=attributeValue .

That is to say, for your case: cas.server.ajp.attributes.packetSize=YOUR
VALUE

Indeed it works now.

Thanks for the hint and sorry for the missread.

You should set packetSize at the same value on application server and in
your web server (we use 16384 in our organization for years).
