Just creating a simple diff in the UI and then trying to create a revision from it with
```
echo '{
"diffid": 822
}
}' | arc call-conduit differential.createrevision
```
fails here with:
```
[HTTP/500] Internal Server Error
{"result":null,"error_code":"ERR-CONDUIT-CORE","error_info":"#1048: Column 'originalTitle' cannot be null"}
(Run with `--trace` for a full exception trace.)
```
