Exception when saving Express Entity

Hello,

I have an Express entity doing 2 One-To-Many associations to another one. I try adding the second one but then I get this error message: Concrete\Core\Entity\Express\Entry::getEntryAssociation(): Argument #1 ($association) must be of type Concrete\Core\Entity\Express\Association, null given. It fails since I added the second association selector to the form. Do you know what can be the issue ?

Hmm - can you maybe try to recreate the steps you took to make this error on a demo site here, and keep track of those steps in a list you could post?

There are a lot of variables otherwise so it’s hard to troubleshoot from afar.
