Reverting to Pendulum < 3.0.0 fixes this issue. Not quite sure the origin of the issue is, will be very communicative in assisting you debug this.

Could you please try to reproduce this on a publicly available project? Your container is based private project and we can't really work with it for debug purposes.

Hi just bumping this :)

Hi. Unless you are willing to debug and fix this issue yourself, you will have to wait until one of the maintainers (there are only two of us) has some time to look into this issue.
