ManiphestCreateTaskConduitAPIMethod::execute() calls ManiphestConduitAPIMethod::applyRequest().
When viewPolicy or editPolicy parameters are set in the Conduit call, make sure to set ManiphestTransaction::setIsCreateTransaction() so the if ($this->getIsCreateTransaction()) checks in PhabricatorApplicationTransaction::getTitle() behave as expected and $this->getOldValue() does not get called when there is obviously no old value.

This also avoids strncmp() complaining about a null value being passed.
