Use LWC in public lightning community

Hello friends. I'm trying to use a LWC in a public community that use the Guest User profile. This LWC uses an Apex method to insert a record Lead. When I call the method I receive this error:  

I also used the lightning-record-edit-form to insert the new record Lead without using Apex method but I receive an error related with ui-api/records, although the information is registered in salesforce.

So, any ideas about this error? Am I missing something important related to LWC?
