Problem with the module signer

#1

Hello,

I am developing some driver modules for Ignition 7.9, I used to self sign modules without any issue. However, since I moved to Ubuntu 18.04 I haven’t been able to. What happens is that although the signing occurs apparently without any issues like it used to, when I install the module I get this errors:

Error installing module

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

The module installs fine If I don’t sign it (with the gateway in dev mode of course). This happened with various versions of Ignition, 7.9.7, 7.9.12 and 7.9.13.

One thing to note is that I was using before (and was working) an older version of the module-signer compiled with java 8. From what I understand this latest version from July needs Java 11 to compile (which was what I did). I’ve also tried compiling that older version again on ubuntu 18.04 with Java 8 and still getting the same error.

Does anyone know what might be going on ?

thanks in advance,
Ricardo

Can you get the full stack trace of the error from the gateway logs?

Hi, sure thing, this is the full error message when I expand it (I tried to attach it as a file but couldn’t as I am a new member). Thanks for the assistance:

This error suggests that the certificate chain file in your module is empty.

Open up the signed module (it’s just a zip) and inspect the contents, see if the chain is really empty or not.

Ah yes, that is indeed the case! There must be some issue with how I generated the chain, I’ll look into it and re-do it. Thank you!
