Have created a tunnel between 10.x.y.z network and 122.a.b.c ..the tunnel is up and active, but when I try the packet tracer output ..I get the ACTION as drop. I have also enabled same-security-traffic permit intra-interface. Can someone help me what does this drop mean?

Result:
input-interface: inside
input-status: up
input-line-status: up
output-interface: outside
output-status: up
output-line-status: up
Action: drop
Drop-reason: (acl-drop) Flow is denied by configured rule
