> Hello.
> We built version 0.12.0 with the ability to execute python scripts as processors
> Made a simple process (see attachment) - calling and getting data using invokehttp get. After that, a custom python processor is executed (see attachment).
> Inside this python script, there is an attempt to get the contents of flow-file. At this point, an error occurs that stops the entire minifi application. At this code line
> !image-2022-11-22-19-46-11-969.png!
> There is a log file where you can see that the error occurs on this line of python code.
> !image-2022-11-22-19-48-08-443.png!
> At the same time, wrapping the python code in try / except does not give anything, apparently the fall occurs somewhere outside the python runtime
> After some time debugging, it turned out that this behavior only occurs when a flow-file is passed from the InvokeHttp processor through the relationship type success
> In this case, the transmitted content is empty (you can connect PutFile and make sure that an empty file will be saved)
> If the relationship type is set to response, then everything works as expected without minifi crashing.
> The expected behavior is that minifi will not suddenly stop if an attempt is made to get the contents of an empty flow-file
