Hi, I'm studding for the ECE and when reading about script processors to be used in ingestion pipelines I see in the documentation that in order to access the field value I should use the ctx variables

_You can access the current ingest document from within the script context by using the `ctx` variable._

I've tried to use doc values but I've compilation errors, I've tried to access to ctx.\_source and I have runtime errors

My question is why the only way to access fields is using ctx. variable

Thank you!  
Regards  
Ana
