Error in Grobid processing one particular pdf file

[AnnaBobasheva]

I noticed an unusual Grobid ERROR in HAL for just one file.

07/11/2023 15:59:44 INFO     /home/issa/ISSA-2/data/hal/pdf_cache/tel-03125685v1.pdf already exists
07/11/2023 16:00:14 ERROR    descriptor 'strip' requires a 'str' object but received a 'NoneType'
Traceback (most recent call last):

    text_list = get_all_text_as_list(root, element_name_or_path)
  File "./extract_text_from_pdf.py", line 102, in get_all_text_as_list
    text_list = [t for t in list(map(str.strip, text_list)) if t]
TypeError: descriptor 'strip' requires a 'str' object but received a 'NoneType'

To figure out what causes the error we need to check the XML /home/issa/ISSA-2/data/hal/dataset-2-0/20231107/xml
