ValueError: Field type I must have length 4 (was 0)

[DmViKe]

Hello,
I'm unsuccessfully trying to open dbf

from dbfread import DBF, FieldParser

class TestFieldParser(FieldParser):
def parse00(self, field, data):
print(field.name, data)
return data
def parseR(self, field, data):
print(field.name, data)
return data

dbf = DBF('c:/base/75.dbf', encoding='cp1251', parserclass=TestFieldParser)
for rec in dbf:
pass

Traceback (most recent call last):
File "C:\Users\Dmitry\PycharmProjects\Transit\Lib\site-packages\Transit.py", line 13, in
dbf = DBF('c:/base/75.dbf', encoding='cp1251', parserclass=TestFieldParser)
File "C:\Users\Dmitry\PycharmProjects\Transit\Lib\site-packages\dbfread\dbf.py", line 123, in init
self._check_headers()
File "C:\Users\Dmitry\PycharmProjects\Transit\Lib\site-packages\dbfread\dbf.py", line 257, in _check_headers
raise ValueError(message.format(field.length))
ValueError: Field type I must have length 4 (was 0)

What does this error mean and how to fix it?

Thanks everyone

I found a problem with my .dbf file.
After manual remove Field "Type" in my database by "DBF Viewer 2000" data is read correctly
But, how do i ignore this field when reading?
