[lag_interfaces]

[Egor-Ozhmegoff]

SUMMARY

I tried to create lag interfaces but i got an error.

FAILED! => {"changed": false, "module_stderr": "'NoneType' object is not iterable", "module_stdout": "", "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error"}

I round the reason for this bug. That happened because i created port-channel without any child interfaces. I manually added one ethernet interface to port-channel and problem had gone.
