I am trying to add a static header to my PostHTTP/InvokeHTTP processor.
As I have gone through the documentation and this answer, it seems like we will support only the attributes from the input flowfile of the processor.
I tried adding the header in the below format, in the attribute Attributes to Send as HTTP Headers (Regex) / Attributes to Send . But it didn't workout.
"key:value"
How can I set a static header which is not part of the flowfile?
