Hi @Link,

Did you fill the tab Order Address Info on the customer address of the specific customer:

Good luck,

Robert

Hi @EqeRobertK 

yes, i did.

Thank you.

Is there an Address ID defined as the default delivery address?

Hi @ShawnBerk 

yes, this is also done. The error message is really strange.

We’ve found the issue. 

The valid to date of the customer address has been passed.

Ahhh good, yes some of the error messages are telling you what is currently failing without pointing to the root problem.  It really is that there is no valid default delivery address which could be fixed by adding a new valid one or by changing the date on the existing customer record.

You should mark your finding as the answer in any case so the post shows as solved.
