flexric's slicing xapp has an error

When trying to run the python xapp_slice_moni_ctrl after having sucessfully run the kpimoni xapp from the instructions in srsrans xapp section there is some issue.

The xapps logs:

I understand that if it is simply not supported yet it may not be possible without some effort on my part, if that is the case can you give some guidelines on how i could approach solving this.

The subscription was rejected by the e2 agent in the gnb, filter the gnb logs with "E2" and share the output.

There you have it. function ID=145 not supported The xapp/ric should read the setup request and only use function IDs the gnb provides, unfortunately its hardcoded in some of the xapps it seems, you just need to change that in the xapp
