Sysrepo Operational Data Callback not working

[chirag-jain12]

We are subscribing to module and registering operational data callback. But when we are doing get via sysrepocfg on operational data, it is failing and not fetching data from callback. Can you please take a look at script and yang models?

Thanks,

While doing get using sysrepocfg, below error is coming:
python3 sysrepocfg.py -d operational -f xml -X ietf-hardware:hardware
python3: sysrepo/src/common.c:4675: sr_xpath_trim_last_node: Assertion `xpath[0] == '/'' failed.
Aborted (core dumped)

Your xpath is invalid. Try with this:

python3 sysrepocfg.py -d operational -f xml -X /ietf-hardware:hardware

Not the same error.

Note that this repo is the python bindings to Sysrepo.

You should probably reach out to the Sysrepo project itself. Have a read at the docs to get a better understanding of the concepts.
