We have a depth field for ostree repos which is a numeric field on the creation page. The note on the page reads that leaving it blank means depth=0 but we don't actually respect that on the backend which requires a value for that field.

When this field is not set on the page, it send null to the API and that is sent as null to pulp which fails. We need to set the value to 0 before we call pulp for ostree repo creation.
