The recording function of FreeSWITCH-1.10.12 seems unable to be enabled properly.

[V-Assassin]

Based on the content of the website https://developer.signalwire.com/freeswitch/FreeSWITCH-Explained/Modules/mod-dptools/6587110/, I have added the following configuration to the file below:
conf/dilplan/default.xml:

<action application="set" data="RECORD_COPYRIGHT=(c) 2011"/>
<action application="set" data="RECORD_SOFTWARE=FreeSWITCH"/>
<action application="set" data="RECORD_ARTIST=FreeSWITCH"/>
<action application="set" data="RECORD_COMMENT=FreeSWITCH"/>
<action application="set" data="RECORD_DATE=${strftime(%Y-%m-%d %H:%M)}"/>
<action application="set" data="RECORD_STEREO=true"/>
<action application="set" data="media_bug_answer_req=true"/>
<action application="export" data="execute_on_answer=record_session E:/recordings/recordings/${strftime(%Y%m%d%H%M%S)}_${caller_id_number}.wav"/>

conf/vars.xml:
<X-PRE-PROCESS cmd="set" data="recordings_dir=E:/recordings"/>

conf/sip_profiles/inernal.xml:

<param name="record-path" value="$${recordings_dir}"/>
<param name="record-template" value="${caller_id_number}.${destination_number}.${strftime(%Y-%m-%d-%H-%M-%S)}.wav"/>

The log output is as follows:

However, the target directory did not generate any audio files.
