'FileDataset' object has no attribute 'FovealSensitivityMeasured'

[gaew25]

Hello,
Thank you for creating hvf-extraction-script 0.0.4!

I saved DICOM file directly from Zeiss FORUM both pdf and DICOM format. I followed your code documentation.
I changed pdf to jpg and thing works well, but for the same patient file in DICOM, it does not work.
Here is what I got:

---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
Cell In[44], line 1
----> 1 hvf_obj = Hvf_Object.get_hvf_object_from_dicom(hvf_dicom)

File ~/anaconda3/lib/python3.10/site-packages/hvf_extraction_script/hvf_data/hvf_object.py:417, in Hvf_Object.get_hvf_object_from_dicom(cls, dicom_ds)
414 hvf_metadata[Hvf_Object.KEYLABEL_LATERALITY] = field;
416 # ===== FOVEA =====
--> 417 field = str(dicom_ds.FovealSensitivityMeasured)
419 if (field == "YES"):
420 field = float(str(dicom_ds.FovealSensitivity));

File ~/anaconda3/lib/python3.10/site-packages/pydicom/dataset.py:908, in Dataset.getattr(self, name)
906 return {}
907 # Try the base class attribute getter (fix for issue 332)
--> 908 return object.__getattribute__(self, name)

AttributeError: 'FileDataset' object has no attribute 'FovealSensitivityMeasured'

I just wonder if I have done anything wrong or there is any error in my own files
sorry I'm not good at coding but Thank you for your kindness:)
