We are facing this issue as well.
Is there any workaround for this or any solution?

Same here. This is a real pain as we're having to pre-process the .xml files before they can be uploaded to the org..

@PabloRoldan
I put a random string instead of empty value and then using apex script I updated metadata that had this random string by changing it to null. Probably it is not the best nor most performant workaround but works.

@pskrzybor
I am doing something similar.
I quoted all the values and the last one I used "null", then I searched for all <value xsi:type="xsd:string">null</value> and I replaced them with <value xsi:nil="true"/>.
Finally, other undefined fields and values are created randomly, so I search for them and delete them using the Find and Replace All tool in VSC.
Thanks for the help 👍

@PabloRoldan @nebc-jasonfung
Here is the apex script I used. Maybe It is going to be helpful. (You need to deploy the metadata first).

Integer counter = 0;
List<DummyCMDT__mdt> DmcdtList = [
        Select id, DeveloperName, MasterLabel, WhatTheText__c
        From DummyCMDT__mdt
];
Metadata.DeployContainer mdContainer = new Metadata.DeployContainer();
for (DummyCMDT__mdt item : DmcdtList) {
    try {
        if (item.WhatTheText__c.equals('AbcxyZ')) {  //The random string placeholder for null value
            Metadata.CustomMetadata metadataRec = new Metadata.CustomMetadata();
            metadataRec.fullName = 'DummyCMDT__mdt.' + item.DeveloperName;
            metadataRec.label = item.MasterLabel;

            Metadata.CustomMetadataValue WhatTheText = new Metadata.CustomMetadataValue();
            WhatTheText.field = 'WhatTheText__c';
            WhatTheText.value = null;
            metadataRec.values.add(WhatTheText);

            mdContainer.addMetadata(metadataRec);
            counter++;
        }
    } catch (Exception e) {
        System.debug(e);
    }
}
if (counter > 0) {
    try {
        Metadata.Operations.enqueueDeployment(mdContainer, null);
        System.debug(counter + ' Metadata records updated');
    } catch (Exception e) {
        System.debug(e);
    }
} else {
    System.debug('0 Metadata records updated');
}

Thank you very much @pskrzybor
I am going to have a look and see how I can integrate it into my script. This will be really helpful to make it automated. I really appreciate it 👍
