hi[mention:c9aac43018464b1c952e96bb390ea8ed:e9ed411860ed4f2ba0265705b8793d05] is your primary key column is configured as auto increment?

check the configurations again

The error arises due to a mismatch between how you're trying to generate IDs for the PFYoutubeDT11569 class and Hibernate's expectations. Possible causes include missing or incorrect ID generation strategy, manual ID assignment requirement, or database configuration issues.

Verify once and let me know if you still have same issue.

Pls Take Care of Your Primary Key. also Verify From DB Side if Auto Increment is done properly or not .
