list input can be bounding box (Nx4) or RLEs ([RLE])

[bowmount]

Hi,
I tried to run evaluate_range for TIDE.MASK but gave an error :
--> list input can be bounding box (Nx4) or RLEs ([RLE])

my dataset dict was like this :
{'_id': 0,
'bbox': [365.0, 436.0, 657.0, 331.0],
'class': 59,
'ignore': False,
'image': 5,
'mask': [[536.4705882352941,
436.1764705882353,
610.5882352941177,
439.70588235294116
]],
'score': 1}

is anything wrong with the structure?
Thank you in advance

I have the same error and did not solved it yet. Is it possible that the gt is not correct?
