Lightning Record Form not working for custom objects in communities

Question

There is a custome object called CutomObject in my sandbox system. I have created a salesforce community to display these objects.

I have created a sharing set on this object type as follows and granted read/write access.

CustomObject.Account = User.Contact.Account

This works fine so that, When I query all the CustomObjects it only extract relevant records. My lightning web component has a model containing following code to view entire CustomObject. (This model appears on abuttonClick)

<lightning-record-form
    record-id="xxxxxxxxxxx"
    object-api-name="CustomObject__c"
    layout-type="Full"
    mode="readonly"
    columns=2>
</lightning-record-form>

But it is not execute properly. Following error appears.

You don't have access to this record. Ask your administrator for help or to request access. INSUFFICIENT_ACCESS

Please note that this error only appears when I log in as a community user. When I log in as the system admin user this is working fine.

Any clue for this?

Answer 1

It seems the user does not have permission to access the particular record type. To enable,

• Type and profiles in SETUP
• Then select the profile related to your community.
• Select Object Settings under Apps
• Change Object Permissions of CustomObject__c to Read from No Access.

Now you are able to use lightning-record-form.
