Image can be None in construct_block function

[fabienheureux]

In the construct_block function, the image variable can be None in some situations, hence failing when trying to access image.id.
I have a suggestion of adding a try / except, in order to fail silently in this case : fabienheureux@99bf46e

Any feedback welcome 👍

Thanks Fabien

Could it be simpler this way?

"image": image_file.id if image_file else None,
