After installing Sprint extension I get following error message when opening "/conduit/method/project.search/"
```
SearchFields "custom:scsOmkpB9Tqi" (of class "PhabricatorSearchCustomFieldProxyField") and "custom:sS__iDJ26B7u" (of class "PhabricatorSearchCustomFieldProxyField") both define the same Conduit key ("custom."). Keys must be unique.
```
