Hello,
I'm coming to you because I have a problem with a customer that I have never encountered before.
I am trying to import data from a saved view of a module to this same module. The saved view uses a filter that allows me to bring the data from an entity X to an entity Y that is selected at each import.
The action works when I launch it directly via Data>Import, or when I edit it before launching it (without changing anything in the mapping). However, it gives me the following error message when I run the action directly without editing first:

The mapping is automatic and is fine when I watch the action détails. After i got the error message, i just have to edit the action, click OK and it works again (until next time!).
Have you ever encountered this problem? Do you have any idea where it could be coming from?
Thank you very much for your help,
