Entity framework error when inserting model

Question

Having problem with inserting a model to database with EF in a MVC application.

Im receiving following error when callning dbContext.SaveChanges() :

[DbEntityValidationException: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details.]

Any clue what this can be about?

Its strange because sometimes it works to make one insert but if i make another immediately after it crashes.

And sometimes it crashes on first insert.

You can check the accepted answer in this post: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details

PS: Please remove error message details as it's of no use and it can expose private information.

More than likely you have some property on the entity that is not nullable. Most of the time when I get this error, that's the culprit. Set a watch on the 'EntityValidationErrors' property, then in the debugger expand into this property and you will see the exact message that is being thrown.
