Please make sure the entity you are going to save is descendant of io.jmix.core.Entity

#3

Actually, io.jmix.core.Entity is added to the class at build time and doesn’t have to be in the source code.
But anyway, something is wrong with your entity class or build scripts.

#4

the entity is created by jmix and idk how to fix it
it’s not happened every time

#5

Set breakpoint to io.jmix.core.impl.UnconstrainedDataManagerImpl.save(UnconstrainedDataManagerImpl.java:136)

and look what value is in the entity id.

#6

ok i will check it
