Hi Kilian

I rebuilt this this morning and translated it from German to English, thought it might be easier.  I created a new server action and my attempt looked something like this:

And I did not manage to fix the error. I did it the way Toto suggested and it now works. Hope I´m on the right way now.

You need to pass an Entity Record as input to the CreateOrUpdate Entity Action, but you supplied a Task Identifier, so that's indeed not going to work.

Note also that it pays off to have consistent naming of your variables, so something that's a Task Identifier should be named TaskId, not TaskImage.

Thank you Toto, it works now.

Hello

I've tried this before as well, but I saw in a course that they use a one to one connection for the images and not a one to many. As I understand it, I need the One To Many connection if I want to attach multiple images to a task, and the One To One connection if I want to attach only one image. Am I correct?

Yes, if you need just a single image, you can use a 1:1 relation. This can be done by:

• Using an existing Identifier for primary key, or;
• Adding a foreign key to the parent Entity.

This as opposed to a 1:many relation where you add the parent Id to the child Entity.
