How am I supposed to understand why the field is confusing?

Good afternoon, colleagues. I have been playing for several hours with this incomprehensible error, how can this be - someone can explain the dependencies of fields between different products, you can link to the documentation, in general the documentation is terrible - you have to look for answers to one question in the track of different links, but this is to the topic does not apply, how to understand the essence of such errors?

When you use a data stream the index names are auto-generated, so you cannot use the index option on the output to set the name.

I may have a difficulty with the logic - help with a resource for learning?
