I created a public site and enable it for customer community login. When I login as a community user, I need to create an Account record. But everytime when I try to create an Account record as a community user, I get the error message saying "OP_WITH_INVALID_USER_TYPE_EXCEPTION, Operation not valid for this user type: []". I rememebered that there is no problem to create Account records with customer portal or partner portal, even if the customer portal doesn't have create permission, since we already run the apex class in system admin mode. But why we can't do that with community user? Did anybody encounter the same problem or know how to solve this problem? Any suggestions will be helpful. Thanks in advance!!
