Description
The LinkedSeries source.id field is optional, but previously
accepted blank values such as empty strings ("") or whitespace-only
strings (" "). This could lead to inconsistent data and unexpected
behavior when processing linked series data.
The Asset API now validates the source.id field and rejects blank
values while still allowing the field to be omitted entirely. If you
send a LinkedSeries request with a blank source.id value, the
request returns a validation error instead of accepting the invalid
data.
Existing LinkedSeries with a blank source.id are not updated
automatically.
