SQL server agent SSIS error

I get the following error when I execute my package as a SQL server agent job.

It is an SSIS 2008 package running on a SQL Server 2008 instance. My package security is DontSaveSensitive.

I don't even know how to begin fixing this error.

Where should I check first?

Date        a value of time
Log     Job History (MyJob)

You have to save the package with EncryptAllWithPassword using a password.

Then schedule it using SQL Agent Job as below :

"DriveLetter\Program Files\Microsoft SQL Server\110\DTS\Binn\DTExec.exe" /FILE "SSIS_Package_Location\bin\Package.dtsx" /DECRYPT "PasswordStrong007" /CONFIGFILE "Location_to_Config_file_If_any\Config.dtsConfig" /CHECKPOINTING OFF /REPORTING E

Now the user account that you use should have permissions on the database server instance.

You can check the permissions using below T-SQL :

SELECT [Login Type] = CASE sp.type
        WHEN 'u'
            THEN 'WINDOWS Login'
        WHEN 's'
            THEN 'SQL Login'
        WHEN 'g'
            THEN 'GRP'
        END
    ,convert(CHAR(45), sp.NAME) AS srvLogin
    ,convert(CHAR(45), sp2.NAME) AS srvRole
    ,convert(CHAR(25), dbp.NAME) AS dbUser
    ,convert(CHAR(25), dbp2.NAME) AS dbRole
FROM sys.server_principals AS sp
JOIN sys.database_principals AS dbp ON sp.sid = dbp.sid
JOIN sys.database_role_members AS dbrm ON dbp.principal_Id = dbrm.member_principal_Id
JOIN sys.database_principals AS dbp2 ON dbrm.role_principal_id = dbp2.principal_id
LEFT JOIN sys.server_role_members AS srm ON sp.principal_id = srm.member_principal_id
LEFT JOIN sys.server_principals AS sp2 ON srm.role_principal_id = sp2.principal_id
