I have been configuring ligthning component and its gone well so far. However I am struggling to find out why the new component doesnt display information, we have reclamation custom objet with lookup relation with contact and I need to display all relamations related to a contact in ligthning component under contact, see bellow all config:

ReclamationListController.apxc
public class ReclamationListController {
        
    @AuraEnabled
    public static List<Reclamation__c> getReclamationList(List<Id> contactIds) {
                List<Reclamation__c> reclamationList = [SELECT Id, Name, Type__c, Description__c, Contact__c FROM Reclamation__c WHERE Contact__c in :contactIds];
        return reclamationList;
    }
}

ReclamationList.cmp

<aura:component implements="flexipage:availableForRecordHome,force:hasRecordId" controller="ReclamationListController" access="global" >
    <!-- Handler to call function when page is loaded initially -->
    <aura:handler name="init" action="{!c.getReclamationsList}" value="{!this}" />
    <aura:attribute name="reclamationList" type="List" />
        <lightning:card title="Reclamations">
        <p class="slds-p-horizontal_small">       
            <aura:iteration items="{!v.reclamationList}" var="reclamation"> 
                <lightning:recordViewForm recordId="{!reclamation.Id}" objectApiName="Reclamation__c">
                    <div class="slds-box slds-theme_default">
                        <lightning:outputField fieldName="Name" />
                        <lightning:outputField fieldName="Type__c" />
                        <lightning:outputField fieldName="Description__c" />
                    </div>

                <br />
            </aura:iteration>
        </p>

        <aura:set attribute="actions">
