Exception on basic company domain lookup

[CalebRoyer]

I get an exception with a basic company lookup, though in Postman I can get a response fine for the same apiKey and domain:

Gradle Dependency:
compile group: "com.fullcontact", name: "fullcontact4j", version: "5.4.0"

Code Snippet:
FullContact fullContact = FullContact.withApiKey(apiKey).build();
CompanyRequest companyRequest = fullContact.buildCompanyRequest().domain("westsidebuildingsupply.com").build();
ci = fullContact.sendRequest(companyRequest);

Stack Trace:
com.fullcontact.api.libs.fullcontact4j.FullContactException: Unknown reason for exception, see stack trace

Looks like your build tool didn't include okhttp on the classpath. It's definitely included in FC4J's:

        <dependency>
            <groupId>com.squareup.okhttp3</groupId>
            <artifactId>okhttp</artifactId>
            <version>3.2.0</version>
        </dependency>

Perhaps your maven/gradle/etc build file is not including it for some reason? Do you have a specific dependency exclusion somewhere?
