The content of the flow file is a parquet file. If the > flow file is processed we are getting a NullPointerException. > > !image-2020-11-11-22-33-31-019.png! > After some tests I found out, that the processor works like expected but if > the flowfile is a parquet file and the reader is a parquet reader it throws > this error. > To confirm that is has to do with the parquet reader, I used a very simple > approach. > Generate flowfile with JSON transform it to parquet and then back to JSON. > This resulted in the same error message. > In the attached Jira_Parquet_Error.json you can see my simple construction. > Here you can see the settings of the parquet writer: > !image-2020-11-11-22-41-13-099.png! > > Here you can see the settings of Parquet Reader > > !image-2020-11-11-22-41-44-188.png! > > Until update from 1.11.4 to 1.12.1 it worked.
