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
