Need help deploying a gradle/spring app to heroku.

I am following along the "Deploying to heroku" video in Chris Ramacciotti's "Deploying a spring application" course. When I run the command "heroku local web", the server appears to start working but then gets killed. The following error is outputted:

4:53:50 AM web.1 | > ConverterNotFoundException: No converter found capable of converting from type java.lang.String to type java.lang.Integer] 4:53:50 AM web.1 | at org.springframework.boot.bind.PropertiesConfigurationFactory.validate(PropertiesConfigurationFactory.java:296) 4:53:50 AM web.1 | at org.springframework.boot.bind.PropertiesConfigurationFactory.doBindPropertiesToTarget(PropertiesConfigurationFactory.java:255) 4:53:50 AM web.1 | at org.springframework.boot.bind.PropertiesConfigurationFactory.bindPropertiesToTarget(PropertiesConfigurationFactory.java:227) 4:53:50 AM web.1 | at org.springframework.boot.context.properties.ConfigurationPropertiesBindingPostProcessor.postProcessBeforeInitialization(ConfigurationPropertiesBindingPostProcessor.ja va:297) 4:53:50 AM web.1 | ... 51 common frames omitted [DONE] Killing all processes with signal null 4:53:51 AM web.1 Exited with exit code 1

Sounds like something in your config is passing a String value when it expecting a int value. Is the code someplace you can share?

^That's all my code. The executable jar file is in the builds/libs folder. When I run "gradlew.bat stage", it builds successfully but when I run "heroku local web", I get this error.

ConverterNotFoundException: No converter found capable of converting from type java.lang.String to type java.lang.Integer]

at org.numberspell.AppConfig.main(AppConfig.java:14)

It appears that the error is referring to the following part of my code:

package org.numberspell;

import org.numberspell.data.Dictionary;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;

@EnableAutoConfiguration
@ComponentScan
public class AppConfig {
    public static void main(String[] args) {
        //loading words into the dictionary
        Dictionary.load();
        SpringApplication.run(AppConfig.class, args);
    }
}

It's referring to the line where is says " SpringApplication.run(AppConfig.class, args); "

What happens when you call Dictionary.load() outside of Spring?
