Hi @WLugaila ,
1.Please check if the user who will run ssis package in sql agent job has permission to access to the SSIS Catalog database.
We can refer to Integration Services Roles (SSIS Service).
2.Please check if you set protection levels in ssis packages.
Encryption
Encryption, as used by package protection levels, is performed by using the Microsoft Data Protection API (DPAPI), which is part of the Cryptography API (CryptoAPI).
The package protection levels that encrypt packages by using passwords require that you provide a password also. If you change the protection level from a level that does not use a password to one that does, you will be prompted for a password.
We can refer to Access Control for Sensitive Data in Packages.
Best Regards,
Mona
