Unable to export tasks as VOC which were created using api

[LouisDealX]

Describe the bug
Tasks with images were uploaded via the api/tasks endpoint. An image was converted to a base 64 string and then attached as image data. Tasks with images appear in UI and I was able to annotate however exporting to VOC I get the following error:

Traceback (most recent call last): File "/usr/local/lib/python3.10/dist-packages/rest_framework/views.py", line 506, in dispatch response = handler(request, *args, **kwargs) File "/usr/local/lib/python3.10/dist-packages/django/utils/decorators.py", line 43, in _wrapper return bound_method(*args, **kwargs) File "/label-studio/label_studio/data_export/api.py", line 200, in get export_stream, content_type, filename = DataExport.generate_export_file( File "/label-studio/label_studio/data_export/models.py", line 161, in generate_export_file converter.convert(input_json, tmp_dir, output_format, is_dir=False) File "/usr/local/lib/python3.10/dist-packages/label_studio_converter/converter.py", line 230, in convert self.convert_to_voc( File "/usr/local/lib/python3.10/dist-packages/label_studio_converter/converter.py", line 1100, in convert_to_voc with io.open(xml_filepath, mode='w', encoding='utf8') as fout: OSError: [Errno 36] File name too long: '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.xml'

Expected behavior
Tasks with annotations should be exported in VOC format and downloaded as a zip file,

Payload used:
payload = { "data": { "image": f"data:image/png;base64,{base64_image}", }, "project": project }

It won't be possible to export images to other formats when you use base64 directly in task data.
