Export/Import Project: From 13.0.6-ee to 13.2.0-pre

The project was developed on a self-contained instance of version 13.0.6-ee. It needs to be exported and then imported into instance of gitlab.com that is currently on 13.2.0-pre. In Version History of the documentation of the Project import/export feature, it says nothing about 13.2.0. Does this mean that I cannot import any projects? Are there any workarounds?

The error that pops up:

P.S. The archive looks fine. I can unzip it and see the files.
