Data Pipeline step 2 throwing exception

[siebeniris]

Hello Simon,

I was able to build up the jar then I tried to implement the step 2 by using the following command:

java -jar out/artifacts/eventkg_jar/Pipeline.jar config.txt 1

my config.txt:

data_folder /Users/XXX/Documents/experiments/eventkg/data
languages en
enwiki 20220301
wikidata 20220302

Then the exception as following is thrown:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1
        at de.l3s.eventkg.pipeline.Config.init(Config.java:59)
        at de.l3s.eventkg.pipeline.Pipeline.main(Pipeline.java:81)

Since I am not really familiar with Java, any help is appreciated, thank you!
