Description

Hello,

under special circumstances GetFile and ListFile do not process files.

To reproduce the problem I attached a template: GetFile-ListFile-Problem.xml

The template generates every minute (0 0/1 * ? * MON-SAT) a flow file of 10B and stores it locally in a new ( ! ) folder: tmp/prod/cltest/${now():format('yyyyMMdd-HHmm')}/gaz/artikel.

GetFile and ListFile run about 30 seconds after GenerateFlowFile processor(35 0/1 * ? * MON-SAT). For both processors the input directory is: tmp/prod/cltest/${now():format('yyyyMMdd-HHmm')}/.
Path Filter is set to: ((anzg)|(gaz))\/artikel

The first time when the processors are running the result set of each processor contains 1 file.
After the first run the result will always be empty. There occurs no error. It's only empty.

We use NiFi versions 1.11.4 and 1.15.2. Both have the same problem.
Could you please have a look on it.

Thank you and regards
Christoph
