StackViewer not working due to offset "out of bounds"

[JwRicauter]

Hi,

I have my app that it was working nice, but suddenly this error jumps out:

Uncaught (in promise) RangeError: offset is out of bounds at Float32Array.set (<anonymous>) at StackViewport._updateVTKImageDataFromCornerstoneImage (StackViewport.ts:1366:1) at StackViewport._updateActorToDisplayImageId (StackViewport.ts:1720:1) at StackViewport.successCallback (StackViewport.ts:1559:1) at StackViewport.ts:1584:1

I don't know what's happening because the image stack viewer was working. I have in my backend NIFTI files from wich I divide it into dicom files and send it to the client.

`
class DicomWeb(generics.GenericAPIView):

class DicomRenderer(renderers.MultiPartRenderer):
    media_type = 'multipart/related; type=application/octet-stream; transfer-syntax=*'

    def render(self, data, accepted_media_type=None, renderer_context=None):
        return data

renderer_classes = (DicomRenderer,)

def get(self, request, study, series, instance, frame):
    case_id = study
    img_id = series
    series_dcms_dir = get_series_dcms_dir(case_id, img_id)
    dicom_path = f'{series_dcms_dir}/{instance}.dcm'
    dicom = pydicom.dcmread(dicom_path)
    data = {}
    data[str(dicom_path)] = (
        'dicomfile', dicom.PixelData, 'application/dicom')

    # encode as multipart_related
    body, content_type = encode_multipart_related(fields=data)
    response = HttpResponse(body, status=200)
    response['Content-Type'] = 'binary/octet-stream'
    return response

`
any clue?
