[logback-user] Logback configuration is coming as null

[Debraj Manna]

Correct restapilayer.logback.xml

<?xml version="1.0" encoding="UTF-8"?><configuration debug="true">

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <encoder>
                %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
            </encoder>
        </layout>
    </appender>

    <root level="DEBUG">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>
