不允许使用GCP DLP对图像类型PNG进行取消识别

Question

我得到了这个错误：google.api_core.exceptions.InvalidArgument:400BytesType.IMAGE_PNG不支持用于取消标识。

我有这个代码，它应该可以处理图像，但后来我收到了这个错误，说它不受支持。我是做错了什么还是相信了错误？这个错误可能是由于我正在试用期吗？

# Construct deidentify configuration dictionary
deidentify_config = {
"info_type_transformations": {
"transformations": [
{
"primitive_transformation": {
"character_mask_config": {
"masking_character": masking_character,
"number_to_mask": number_to_mask,
}
}
}
]
}
}
# Construct item
bucket = storage_client.get_bucket(SENSITIVE_BUCKET)
blob = bucket.get_blob(file_name)
item = blob.download_as_bytes()
file_extension = os.path.splitext(file_name)[1]
print("File extension is: " + file_extension)
contentItem = {}
if file_extension == '.jpg':
contentItem = {"byte_item": {"type_": 1, "data":item}}
elif file_extension == '.bmp':
contentItem = {"byte_item": {"type_": 2, "data":item}}
elif file_extension == '.png':
contentItem = {"byte_item": {"type_": 3, "data":item}}
elif file_extension == '.svg':
contentItem = {"byte_item": {"type_": 4, "data":item}}
else:
contentItem = {"value": item.decode()}

只有在RedactImage方法中才支持图像。
