Hi Michael, it’s been a while and we have not encountered this error recently and thus have not been able to provide you with more details. However the problem still exists as far as we know. Reading the blogpost on the release of Vendure 1.3, the new with transaction() reminded me of this issue. This might be the perfect occasion for it? If needed I can try to plan in some time to create a repo that reproduces this issue.
