How to solve bug with 1c and big image files?

Question

opencart

Good afternoon, I made an integration with 1c products. The upload goes fine every 2 hours (under development) the problem is that there is a bug (in the 1s module itself) that the old images are not deleted. Rather, even weight is added to new files. And now, after 10 days of development, the weight of one image reaches 200mb. I think who uses the module 1s faced such a problem. How can this problem be solved?
