Impossible to save server script "Unknown column 'storage_service_id' "


Whenever I try to save a script under "database._table.{my_table_name}.get.post_process, I get such an error:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'storage_service_id' in 'field list' (SQL: insert into 
`event_script` (`name`, `type`, `content`, `is_active`, `allow_event_modification`, `storage_service_id`, `scm_repository`, 
`scm_reference`, `storage_path`, `created_by_id`, `last_modified_date`, `created_date`) values 
(database._table.participant.get.post_process, v8js, //var resource = event.response.content.resource;
var processedResource;
, 0, 0, , , , , 1, 2017-11-27 15:50:57, 2017-11-27 15:50:57))

In case it is relevant, the language of the Script is V8js.

Did someone run into a similar issue? Any idea what I could do?

Thanks in advance!
