Hey @krimo,

This should be now fixed on main with Add empty lockOwner and lockExpirationTime getter / setter on the v5 … · flowable/flowable-engine@1a4ed89 · GitHub.

Cheers,

Hello,
Thanks you for the hep.
I understand that you have fixed it on the main branch, the problem is that we are using openidm 7.4.1 that uses flowable 6.8.0, so the problem is not fixed in this case.
