How can I save empty values in metafields

I am working on a checkout ui extension and I notice that after I type some values into a field whose value updates a metafield and I try to reset the value of the field to an empty string via the code, the `updateMetafield` function wouldn't accept the empty string. Is there a workaround to update metafields with empty values.

Hi Turbofan1178,


The issue you are experiencing may be due to the way the updateMetafield function handles empty strings. In some cases, the function might interpret an empty string as null or undefined, and hence ignore the update.


A potential workaround could be to use a placeholder or default value instead of an empty string. For example, you could use a space " " or some default text like "N/A" or "Not provided". Test this out and see if it's suitable for your usecase.
