Getting error no registration found for callpoint

Hi ,
While trying to execute (netconf-console-tcp --host=10.24.7.52 -port=2023 cmd-get-hw-inventory.xml),i am getting error :
no registration found for callpoint cb_op_hw_component/get_attrs of type=external
devel-c no registration found for callpoint cb_op_hw_component/get_attrs of type=external path /hw:hardware/component{ALTIOSTAR-RRH}
25-Jan-2022::06:47:00.775 kontronbng18 confd[21241]: netconf id=14 couldn’t retrieve all data from the data providers, closing session

when i execute confd --status shows:
callpoints:
id=cb_op_ald_cs daemonId=1 daemonName=Operational callbacks=get_elem
id=cb_op_ald_ports daemonId=1 daemonName=Operational callbacks=get_next,get_elem
id=cb_op_bc daemonId=1 daemonName=Operational callbacks=get_case,get_next,get_elem,exists
id=cb_op_delay daemonId=1 daemonName=Operational callbacks=get_next,get_elem
id=cb_op_hw_component daemonId=1 daemonName=Operational callbacks=get_next,get_elem

when i execute confd --check-callbacks:
/hardware/last-change - exists()… ok
/hardware/last-change - get_elem()… ok
/hardware/component - get_next(-1)… ok
/hardware/component[name=‘ALTIOSTAR-RRH’] - exists()… ***: reported as no exist
/hardware/component - get_next()… ok
/hardware/component - num_instances()… ok

cmd-get-hw-inventory.xml:

<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="1">
<get xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
<filter type="subtree">
 <hardware  xmlns="urn:ietf:params:xml:ns:yang:ietf-hardware">

]]>]]>
<?xml version="1.0" encoding="UTF-8"?>
 <rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="2">
<close-session/>
</rpc>

Also I have added the debug message in get_next call back which i could see.
if anyone can help me what could be the probable reason then it will be really helpful to me.

Hi,
Either register the get_attrs() callback or set /confdConfig/enableAttributes to false in your confd.conf
See the confd_lib_dp(3) and confd.conf(5) manual pages for details.

Hi Conny,
Extremely sorry for late reply.
Thanks a lot for finding the root cause. Really appreciate your analyzing and finding the root cause.
