Empty <ObjectApiName>.object-meta.xml after sfdx cli pull command

Question

I have a custom object. In the new scratch org I changed a custom button URL of the object using Salesforce UI. Then I run sfdx force:source:pull and retrieved 2 changed files: the changed weblink and the object's xml. Weblink file is fine but the object xml file is broken as it's content vanished.

My <ObjectApiName>.object-meta.xml before the pull:

<?xml version="1.0" encoding="UTF-8"?>
<CustomObject xmlns="http://soap.sforce.com/2006/04/metadata">
    <actionOverrides>
        <actionName>Accept</actionName>
        <type>Default</type>
    </actionOverrides>
    ...
    ...
    <sharingModel>ReadWrite</sharingModel>
    <visibility>Public</visibility>
</CustomObject>

after:

<?xml version="1.0" encoding="UTF-8"?>
<CustomObject xmlns="http://soap.sforce.com/2006/04/metadata">
    <enableEnhancedLookup>true</enableEnhancedLookup>
</CustomObject>

Why it happened and how to make it preserve the object's xml?

Answer 1

As far with the tests I made the org just pulls the changes you did or the metadatas you explicity put in the package.

If you want to get everything whithin the Object you should get all CustomFields, all Actions, etc. and the Object you want, for example.

<types>
    <members>*</members>
    <name>CustomField</name>
</types>
<types>
    <members>MyCustomObject__c</members>
    <name>CustomObject</name>
</types>
