The bottom of your error states `Placeholder value is found. Please specify valid configuration for State Store database`.

This means that the state configuration (which you can find in the cd_deployer_conf.xml contains some placeholder value (${...}) instead of an actual value.
This is the state store configuration block :

    <State>
        <Storage Adapter="${dbadapter}" driver="${dbdriver}">
            <Property Name="host" Value="${dbhost}"/>
            <Property Name="port" Value="${dbport}"/>
            <Property Name="database" Value="${dbname}"/>
            <Property Name="user" Value="${dbuser}"/>
            <Property Name="password" Value="${dbpassword}"/>
            <Property Name="validationQuery" Value="${dbvalidationquery}"/>
        </Storage>
    </State>

You could either make sure that either you replace these placeholder values with actual values, or that you set an environment value for each of these.

If you want to know the values to use (it should be possible to reuse the same DB as your regular Broker DB), you should check the examples (that are commented out in the same xml file) provided for oracle or sql server.
