NPE when trying to remove stopwords when creating a collection.

[SimeonEvorra]

Hello

I need to remove some stopwords but got the following error (on the 6.1.0)

java.lang.NullPointerException: Cannot invoke "java.util.List.addAll(java.util.Collection)" because "this.removals" is null
	at io.weaviate.client6.v1.api.collections.InvertedIndex$Stopwords$Builder.remove(InvertedIndex.java:122)
	at io.weaviate.client6.v1.api.collections.InvertedIndex$Stopwords$Builder.remove(InvertedIndex.java:117)

Here is a code sample to reproduce:

var test = weaviateClient.collections.create("TestCollection",
         col -> col.properties(Property.text("test", p -> p.vectorizePropertyName(false)))
            .vectorConfig(VectorConfig.text2vecOpenAi(cfg -> cfg.model("ada")))
            .invertedIndex(inv -> inv.stopwords(sw -> sw.remove("it"))));

Or is my approach incorrect and that's not the way to remove stopwords?

Thank you

hi @SimeonEvorra! your approach is correct -- indeed there's bug in the library code.
I'll fix it for you in the next patch release.
