Non mandatory slug field not saving due to invalid format when empty

Hi everyone,
I’m experiencing a strange new behavior for a non mandatory slug field based on my item title field.
Until yesterday, I was allowed to leave the field blank for the home page by means of manual edit. Now I cannot do that anymore, even though the field is not mandatory.

Is it working like that by design from now on or is it some sort of bug?

hello @federico, welcome! :slight_smile:

Have you checked that your slug field is not maybe unique:

That would mean that you cannot have two empty slugs. If that’s not the case please share your project so that I can have a look. Either here via private messages or over https://www.datocms.com/support

Yes, already checked that. Sending you the details in the support channel

Just a quick followup for everyone. It was an error on our side that has been resolved.
