Document processing shows 0 records after running indexer.py script

[FatemaD1577]

I am trying to create a knowledge graph for a custom schema.

My input data is pdf files. So I have used dir_file_scanner.

Schema commit has been done successfully and I can see the my entity types in the knowledge model.

As per the documentation, after this process we need to run the indexer.py file. There are no errors/warnings but it shows there is 0 data to process.

Even the chkpt file is empty. I dont know what am I missing.

Guidance would be highly appreciated.

Thanks in advance.
