key error when using "florence2 Coordinates" bbox to Sam2segmentation

[danyuexiao]

keep receieving this key error when i use the sam2segmentation node.
i basically use the florence2 node's phase grounding feature to get the bbox coordinates of an object in the image. and then pass it to the
sam2segmentation node to convert it to a mask.
but no matter what i set the index to in the "Florence2 Coordinates", it always returns an error saying key error to me.

and i looked at the info, the data structure of the Data seems not matching the way the node extract the bbox?

got prompt
head<loc_333><loc_156><loc_725><loc_664>
match index: 0 in mask_indexes: ['0']
