Jasper Rest_v2 request returns an empty response even the data is there

I am trying to get the list of reports available in a directory of the jasper report server but it returns this response after a get request

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <folder>
    <creationDate>2020-09-17T15:55:48</creationDate>
    <description></description>
    <label>reports tester</label>
    <permissionMask>1</permissionMask>
    <updateDate>2020-09-17T15:55:48</updateDate>
    <uri>/reports_tester</uri>
    <version>0</version>
    </folder>

here is my link to the folder.

    http://myserver:port/jasperserver/rest_v2/resources/reports_tester?type=...
if I use the below link, it says **TIBCO Jaspersoft: Page Not Found**    
    
    `http://myserver:port/jasperserver/rest/resources/reports_tester?type=rep...`

here is the data in the specified folder.
