“Save to File” Button Creates Empty File

### Expected Behavior

I want to save responses larger than 5MB to a file, because otherwise the UI becomes unresponsive.

### Actual Behavior

When I click “Save to File,” the saved file is empty and does not contain the expected response.

### Reproduction Steps

1) Call an API with a large response
2) Click "Save To File"
3) "Save Response Body" Dialog opens
4) Choose a file name and file type and click Save
