Encountered this problem on latest django/imagekit/storages, can confirm workaround #391 worked for me.

This issue is resolved inside the repo after [this](https://github.com/sidorares/json-bigint/commit/3530541b016d9041db6c1e7019e6999790bfd857) commit, but for some reason author doesn't seem too interested to publish it on npm.
