@enam  Looks like you have a bad file filter regex in your listSFTP processor configuration. .*file.*\.xls Above looks for any character for 1 or more characters until is finds the last occurrence of string "file" followed by any character for as many characters until last occurrence of string ".xls".  However, all your filenames start with "file" and have no characters before it. Try modifying your file filter regex by removing the ".*" before "file": file.*\.xls  Right click on processor, select "view state", and then "clear state".  Then start the listSFTP processor again to see if generated NiFi FlowFiles for each file on your SFTP server.

@Anderosn  Is your InvokeHTTP processor triggered by a FlowFile from an inbound connection to the processor or does it have no inbound connections and executes purely based on configured run schedule? This is one of very few processors where an inbound connection is optional, but behavior is different dependent on the configuration chosen.   With no inbound connection there is no FlowFile to "retry" when you encounter "failure" or "No retry" result from execution.  Because really it is retrying every time it executes essentially with no inbound connection. You could use a GenerateFlowFile processor to feed an empty trigger FlowFile to the invokeHTTP processor to trigger its execution.  This would then give you a FlowFile that Retry configuration can use.

@FrankHaha  Have you tried using the "Infer Schema" Schema Access Strategy in the JsonTreeReader 1.24.0 controller services instead of fetching schema from AvroSchemaRegistry?    Another option would be to use the ExtractRecordSchema 1.24.0 processor along with JsonTreeReader 1.24.0 controller services configured with "Infer Schema" Schema Access Strategy" to output the schema into a FlowFile Attribute "avro.schema".  You can then get the produced schema from that FlowFile Attribute to add to your AvroSchemaRegsitry for future use.
