SSIS Parent Pkg failing

Hi,

I am created SSIS parent package that is suppose to call 14 child packages. But due to issues, I am trouble shooting with one child pkg. Actaully the pkg calls child successfully and run it but then parent pkg fails for that child. I have created new parent pkg to avoid this connection error but no success. Can anyone please help where I am wrong?

here is my error

Error: 0xC001000E at : The connection "{C7F0DCCE-0AE0-4560-92D7-AA641B573223}" is not found. This error is thrown by Connections collection when the specific connection element is not found.
