[SalesForce] LWC: How to get access to proper Error message when statically calling an Apex method from LWC

I call an Apex method statically.

    @AuraEnabled
    public static Id insertx(){
insert new Account();
}

From a LWC component:

insertx().then( () => {})
.catch(error => {this.error = error;})

My problem is that the message returned is:
"An internal server error has occurred Error ID: 830852859-43925 (1007478720)"

Anyone knows how to get a proper message from Apex?
I also tried using a try/catch and throwing an AuraException but it gave the same result

try{
// a required field is missing
insert new Account();
}
        catch(Exception e){
            Database.rollback(sp);
            System.debug(Logginglevel.ERROR, e.getMessage());
            throw new AuraException(e.getMessage());
        }

You don't have to throw AuraException, instead, you have to throw

AuraHandledException (for Aura components only)

AuraHandledException (for LWC components)

 @AuraEnabled
    public static string insertAccount(){
        try{
        // a required field is missing
        insert new Account();
        }
        catch(Exception e){
           
            System.debug(Logginglevel.ERROR, e.getMessage());
            throw new AuraHandledException(e.getMessage());
        }

        return null;
    }

In Console:

{"ok":false,"status":400,"statusText":"Bad Request","body":{"message":"Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Account Name]: [Account Name]"}}

Throwing any exception other than AuraHandledException gives internal server error.
