Describe the issue or problem
I expected a Successful message from an upgrade above but I got error during the upgrade:
ERROR: Upgrade failed: DB: SQLSTATE[22007]: Invalid datetime format: 1366 Incorrect integer value: '' for column `ojs`.`doi_settings`.`doi_id` at row 1 (SQL: insert into `doi_settings` (`doi_id`, `setting_name`, `setting_value`) values (, registrationAgency, DataciteExportPlugin))
Steps I took leading up to the issue
For example:
- Downloaded version 3.4.0-10
- Prepared configurations
- Resolved all errors (Always restore from backup on every single failed attempt and re-applied all fixes)
- Run upgrade tool command and about a dozen attempts trying different resolution from the web and the OJS forums but still resulting with the same error above.
What application are you using?
OJS 3.3.0-20 attempting to upgrade to 3.4.0-10
