Hi, I am trying to use NIFI REST API to send data to an input port for testing.  I have created the transaction and I have received a transactionId. After that, I have tried to send data by using /flow-files but I have received this error :   {"flowFileSent":0,"responseCode":250,"message":"org.apache.nifi.remote.exception.ProtocolException: FlowFile exceeds maximum number of attributes with a total of 1952805748"} My input  :  URL : https://localhost:8080/nifi-api/data-transfer/input-ports/abcc394c-7a49-1a38-0ddc-c79ffbe1f4c6/transactions/ac467cda-28e9-40d0-9738-619d5a07ac28/flow-files Headers :   Do you have an idea to solve my issue? Thanks in advance.      ... View more
