[Dbix-class] DBIx::Class - Create

[Alexander Hartmaier]

I had the same message last week.
It happens when your Result(Set) object loses its schema.
That might happen because of freeze/thaw, in my case because of
Parallel::Iterator which does use Storable internally.

The fix is to insert this line before you serialize the object:

# to let DBIC automatically pick up the correct schema in the child
# process after Storable freezed/thawed the result objects
local $DBIx::Class::ResultSourceHandle::thaw_schema =
$rs->result_source->schema;
