Graphs don't display in i2p console - error 500

    • Closed Issue created by Ghost User @ghost

    When I go to /graphs in the i2p console, the graphs don't load. I get error 500 in the browser console and this error on the logs page: [le Jetty-923] rg.eclipse.jetty.server.Server: : javax.servlet.ServletException: java.lang.InternalError: java.lang.reflect.InvocationTargetException

    I am using the docker container version 2.1.0-1 and everything else works apart from these graphs.

      it should be right under the "InvocationTargetException" on the logs page. Look in all three boxes - critical logs, router logs, and wrapper logs

      if you don't see it, add org.eclipse.jetty.server.Server=WARN to the override section on /configlogging , click save changes, then try to trigger the error again.

      you may only get the error once though? I think we may remember that it failed and not try again? If so you might have to restart to get the error again.

      thanks

        Since it's docker, I'll also ask @idk to please try to reproduce

        As I had installed docker on a VM any way, I gave this a shot ... Got a router up rather easily, basically with

        root@test:~# apt install docker.io
root@test:~# docker pull geti2p/i2p
root@test:~# docker run -p 7657:7657 -v i2phome:/root/i2p geti2p/i2p

        and was able to reproduce what OP described. So I set the logging as you suggested and got this with it:

        you may only get the error once though?

        If emptying the log and going to the graphs page again there is no new log generated here, indeed.

        Here the versions as I get them:

        I2P version:	2.1.0-2
API version:	0.9.57
Java version:	Alpine 17.0.3 (OpenJDK Runtime Environment 17.0.3+7-alpine-r0)
Wrapper version:	none
Server version:	9.3.30.v20211001
Servlet version:	Jasper JSP 2.3 Engine (3.1)
JSTL version:	standard-taglib 1.2.0
Platform:	Linux amd64 5.10.0-20-amd64
Processor:	Ryzen/Epyc model 49 (zen)
JBigI status:	Native BigInteger library libjbigi-linux-zen_64.so loaded from resource
GMP version:	6.2.0
JBigI version:	4
JCpuId version:	3
Encoding:	UTF-8
Charset:	UTF-8
Service:	false
Built By:	unknown

        Some things I noticed here:

        • Wrapper version: None >> on Debian installs I get a version displayed here
        • Built By: unknown >> I didn't do this, the Docker image is from DockerHub or whatever. On Debian installs I get "undefined" instead of "unknown", however.

        @idk I don't know anything about Docker or where or how it gets built, but could you add build.built-by=Docker to override.properties as a part of the build process?

        Or maybe build.built-by=Docker Hub, to make even more clear where it's coming from

      Thanks lbt for getting the stack trace before anybody else got to it.

      Did basic workaround to catch the error, give a better error message, and disable graphing.

      In b8815fc6 to be 2.1.0-3

      Assigning to idk to identify/fix the problem which is related to (not) installed fonts, and the built-by issue.
