heroku local web is not processing

Question

I'm trying to run my telegram bot on heroku but currently after i type in

heroku local web

inside git it doesn't seem to terminate or infact do anything on screen

Screenshot here

What i've done so far

1) Followed the instructions found here https://devcenter.heroku.com/articles/preparing-a-codebase-for-heroku-deployment

2) made sure my pom.xml file has the proper dependencies (snippet below).

    <properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

<dependencies>

    <dependency>
        <groupId>com.vdurmont</groupId>
        <artifactId>emoji-java</artifactId>
        <version>3.1.3</version>
    </dependency>

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-simple</artifactId>
        <version>1.6.1</version>
    </dependency>

    <dependency>
        <groupId>org.telegram</groupId>
        <artifactId>telegrambots</artifactId>
        <version>4.8.1</version>
    </dependency>
</dependencies>

<build>

    <plugins>
        <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <archive>
                    <manifest>
                        <addClasspath>true</addClasspath>
                        <mainClass>Main</mainClass>
                    </manifest>
                </archive>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
            </configuration>
        </plugin>

    </plugins>
</build>

3) Played around with the Procfile heroku needs (shown below)

web: java -jar target/FastFoodSG-1.0-SNAPSHOT-jar-with-dependencies.jar

4) for reference this is how it's supposed to look like

Correct output

5) here are the logs too
