The error message indicates that there is an issue related to a null value in the "date" column of the "account_move" relation. Even though the error message mentions the "account_move" table, the actual problem might be related to a different part of your configuration. Here are some steps to troubleshoot and resolve the issue:

1. Check Dependencies:
   • Review the dependencies of the modules installed in your Odoo instance, especially those related to manufacturing, accounting, and inventory.
   • Ensure that all required modules are installed and updated to compatible versions.
2. Review Manufacturing Order Configuration:
   • Inspect the configuration of the manufacturing order in the "mrp.production" module.
   • Verify that all required fields, including those related to dates, are properly configured.
3. Check Bill of Materials (BoM):
   • If your manufacturing order involves the creation of a product, review the associated Bill of Materials (BoM).
   • Ensure that the BoM is configured correctly, and all components have valid dates.
4. Inspect Work Orders:
   • Manufacturing orders in Odoo are often associated with work orders. Check the configuration of work orders related to the manufacturing order in question.
   • Verify that the work orders do not have any inconsistencies or missing values.
5. Review Accounting Configuration:
   • Although the error message mentions "account_move," it might be related to a broader accounting configuration.
   • Check the accounting settings, including chart of accounts, fiscal positions, and related configurations.
6. Inspect Custom Code:
   • If you have any custom modules or code related to manufacturing, accounting, or inventory, review the code for any potential issues.
   • Look for customizations that might be triggering actions in unexpected ways.
7. Check for Database Inconsistencies:
   • Odoo provides a tool to check for database inconsistencies. You can find it in the developer mode under "Technical" -> "Database Structure" -> "Database Check."
8. Log Files:
   • Review Odoo log files for any additional error messages or stack traces that might provide more information about the root cause of the issue.
9. Update Modules:
   • Ensure that all installed modules are updated to their latest versions. Odoo updates often include bug fixes and improvements.
10. Seek Community Assistance:

• If the issue persists, consider seeking assistance from the Odoo community forums or contacting Odoo support. Others may have encountered similar issues and can provide insights.

1. Database Backup:

• Before making any significant changes or attempting to fix the issue, it's advisable to create a backup of your Odoo database.

By systematically reviewing these areas, you should be able to identify the root cause of the issue and take appropriate steps to resolve it. If you have specific details about the manufacturing order, work orders, or related configurations, they might provide additional clues for troubleshooting.
