Export in COCO format - error

[YamenMHR]

After annotating some data, I tried to export the annotation in COCO format, but I am getting the error: 'NoneType' object has no attribute 'filename

please provide me with the following:

• what input mode did u use (Image/directory/video/video as frames)
• what model did u use for annotation

[YamenMHR]

• As input, I tried using image and directory. Both options resulted in the same error.
• I tried SAM vit_h and also creating a polygon manually.

I checked it now, This error happens when you try to export your annotations without having the annotation files ".json"

I think the senario was as following, and please correct me if I'm wrong: "When you open an image, the export button is disabled by default ,when you press save it's enabled and you can export your annotations, the problem is that you pressed on save button, then closed the dialog without saving the annotation file, then you tried to export and got that error"

For now: make sure you have the annotations saved in ".json" file, and we will fix this by preventing such a senario, thank you for your feedback.

That is exactly what happened. Thanks for the fast response.
