Hi,

I am facing a strange issue.
I am trying to create a record using lightning:frecordEditForm but not able to create a record.
I have a master detail relationship field "Account" on object "Book". When I have change the relation to lookup it is working. But for master detail relationship it is not working. Please help me.

Below is the code
<aura:component implements="force:hasRecordId,flexipage:availableForAllPageTypes">
     <aura:attribute name="recordId" type="Id"/>
     
    <lightning:recordEditForm  objectApiName="Book__c">
        <lightning:messages />
        <lightning:inputField fieldName="Name" />
        <lightning:inputField fieldName="Account__c"/>
        
        <lightning:button class="slds-m-top_small" type="submit" label="Create" />
    </lightning:recordEditForm>

</aura:component>
