In our use case we have two seach_api index sett-ups; one for local development and one for staging / produdction.
On deployment we use drush cset search_api.server.index status false to select the appropiate configuration.
This works fine for trash and rebuild on the local development machines, but when the configuration in imported on the persitent environments the following error is produced:
