BigInt is not defined. Error in Webconsole

I'm moving from a Windows based PROTECT server to a Linux one (as the Windows system is a little overwhelmed).

While I've followed the instructions as stated in https://help.eset.com/protect_install/10.1/en-US/prerequisites_server_linux.html?component_installation_server_linux.html, there were a few changes that I had to make, particularly the Tomcat installation part had the old tomcat7 installed when I required tomcat9.  (Note: in https://help.eset.com/protect_install/10.1/en-US/prerequisites_server_linux.html?component_installation_webconsole_linux.html, 

for CentOS, yum install tomcat installs version 7. 

Anyway, after putting the era.war in the webapps directory, I tried to log in but got the following error:



*locale: en_US*
*user.agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0 SeaMonkey/ (gecko1_8)*
An uncaught exception has occurred! (" BigInt is not defined ")

I had installed tomcat-native 1.2.35 (but it looks like the latest is needed - 1.2.39, but I haven't updated that as it requires the JDK; but since the webconsole is running, I'm guessing it is an option? 

Anyway, might anyone have any idea of what this issue is caused by?  

I have installed the following:

  • Server: 10.1.2270.0
  • Agent: 10.1.2272.0  (x86-64)
  • Webconsole:
  • Tomcat:
  • CentOS: 7.2.1511

Any help appreciated.

I think I found out what the problem was.  SeaMonkey and some old version of Firefox isn't compatible to the webconsole.  Using a newer version of Firefox 'avoided' the error.
