Please weight field set to 0.
"7.3.4.2 Modify Group Entry Message" in OFspec1.3.4 says:
The weight field is only defined for select groups,
and its support is optional. For other group types,
this fields must be set to 0.
And, I would recommend you to use --verbose option as follows.
ex.
# ryu-manager [app_name] --verbose
Then, it may becomes easier to find out errors.
