Reporting Server - Manifest.json error with reverse proxy

I solved the issue:

* Add an application in Default Website

* Add the following mod-rewrite rules to the config that resides inside the location path:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <clear />
                <rule name="ReverseProxyInboundRule1" enabled="true" stopProcessing="true">
                    <match url="(.*)" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
                    <action type="Rewrite" url="http://localhost/Reports/{R:1}" appendQueryString="true" />
                </rule>
                <rule name="ReverseProxyInboundRule2" stopProcessing="true">
                    <match url="(.*)" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                        <add input="{CACHE_URL}" pattern="^(https?)://" />
                    </conditions>
                    <action type="Rewrite" url="{C:1}://localhost/Reports/{R:1}" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>
