Not able to insert image in fillable from field of type image.

[oreanroy]

Some fillable pdf templates have image fields.
When I try to update a text, and checkbox field, it works fine.
However, when I try to update the image field, It fails.

Here is the code sample to replicate the same issue and the same pdf, JSON file to mimic the behaviour.
