issue for converting to bert_data

[connie-n]

I tried to json data to bert data(data preprocessing step 5) but it returned empty file..
could anyone help me?

I run this code with both cnndm and my own data. cnndm data was converted to bert data successfully but my own data wasn't.
I adjusted the min_src_tokens/min_tgt_tokens but it is still not working.

for json_f in glob.glob(pjoin(args.raw_path, '.' + corpus_type + '.[0-9]*.json')):
