For a while now I’m trying importing contacts via csv import.  
  
I map all the fields into mautic and everytime i get the following error:

Code:

(#327) A new entity was found through the relationship 'MauticLeadBundleEntityListLead#lead' that was not configured to cascade persist operations for entity: Proxies\_\_CG\_\_MauticLeadBundleEntityLead with ID #21308. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example @ManyToOne(..,cascade={"persist"}).

  
It's not selfhosted version, but paid Mautic Cloud. Anyone knows what's the problem?
