Symptoms

The initial setup was performed without specifying a File storage:

The path for the File storage was added after some time:

During the document processing, an error occurs:

Unable to access Project's options. This object is corrupt ().

Cause

The error is caused by adding a File storage path after the database was created.

Resolution

File storage can only be created when creating a database and cannot be created later while processing documents with FlexiCapture.
If it is required to migrate from Database schema to Database + File storage schema, please consider the following actions: 

1. Remove the File storage path from settings, to make the project available again.
2. Stop automatic import and finish processing the current batches as all the data will be lost.
3. Export projects from the server to some local storage manually or by CLI command: DownloadProject
4. Create a new database with File storage specified.
5. Upload previously exported projects.
