WSO2EI 7.1.1 File Processing not working on centos server - apache

Question

I am trying this tutorial from this given link https://ei.docs.wso2.com/en/latest/micro-integrator/use-cases/tutorials/file-processing/
Here is the file proxy definition
<?xml version="1.0" encoding="UTF-8"?>
<proxy name="daily-file-proxy" startOnLoad="true" transports="vfs" xmlns="http://ws.apache.org/ns/synapse">
<target>
<inSequence>
<log level="full"/>
<clone>
<target sequence="daily-file-file-write-sequence"/>
<target sequence="daily-file-mail-notification-sequence"/>
<target sequence="daily-file-db-sequence"/>
</clone>
</inSequence>
<outSequence/>
<faultSequence/>
</target>
<parameter name="transport.PollInterval">15</parameter>
<parameter name="transport.vfs.ActionAfterProcess">MOVE</parameter>
<parameter name="transport.vfs.MoveAfterProcess">$FILE:FILE_DAILY_PROCESS</parameter>
<parameter name="transport.vfs.FileURI">$FILE:FILE_DAILY_DOWNLOAD</parameter>
<parameter name="transport.vfs.MoveAfterFailure">$FILE:FILE_DAILY_FAILURE</parameter>
<parameter name="transport.vfs.FileNamePattern">.*.txt</parameter>
<parameter name="transport.vfs.ContentType">text/plain</parameter>
<parameter name="transport.vfs.ActionAfterFailure">MOVE</parameter>
</proxy>
I also declared all the parameters in the file.properties as well.
This code worked properly from Integration Studio as I drop the txt file in the FILE:FILE_DAILY_PROCESS, it processed in 15 sec and put the data into database.
Then I packaged the project as car file and deployed to micro integerator wso2 in the centos server.
I checked the log and everything deployed properly without error (wso2carbon.log and wso2-error.log not show any error)
I am thinking that the wso2ei could not see the folder declaring
Here is the parameters declaring in file.properties
FILE_DAILY_DOWNLOAD=file:///root/file-processing/daily-download/202107
FILE_DAILY_PROCESS=file:///root/file-processing/daily-process
FILE_DAILY_PROCESS_URI=vfs:file:///root/file-processing/daily-process
FILE_DAILY_FAILURE=file:///root/file-processing/daily-failure

Answer 1

finally, I have figured out the issue. The wso2 could not see the specific folder under ssh user root. It must be under /home/wso2 so the VFS listener only see the folder available under /home/wso2 folder
So use the update settings
FILE_DAILY_DOWNLOAD=file:///home/wso2/file-processing/daily-download/202107
FILE_DAILY_PROCESS=file:///home/wos2/file-processing/daily-process
FILE_DAILY_PROCESS_URI=vfs:file:///home/wso2/file-processing/daily-process
FILE_DAILY_FAILURE=file:///home/wso2/file-processing/daily-failure
