I am using the latest Tomcat 10.1

Apache Web server communicates with an application server running tomcat. The
application name is webtools.
I am migrating a working app from Tomcat 9 to Tomcat 10.1.
Does your AJP connector in Tomcat 9 have a packetSize attribute? If yes,
you need to copy that across to 10.1
You can also check your work configuration on httpd for max_packet_size.
The two values have to agree.

I am getting this error in the tomcat app after sending a web request. It seems
like it is starting to load things. Then I see the below:
