Developing an extension - getting access to the core

Hi,

can anyone advise why this code leaves me with config === undefined ?

class PagesAPIHandler extends APIHandler {
    constructor(addonManager) {
        super(addonManager, manifest.id);
        addonManager.addAPIHandler(this);

        let pages_db_location = '/home/pi/.mozilla-iot/pages';    // hard-coded fallback

        const db = new Database(manifest.id);
        db.open().then(() => {
            db.loadConfig();
        }).then((config) => {
            if (config && config.dblocation) {
                pages_db_location = config.dblocation;
            } else {
                console.error(`pages-api-handler (B): "dblocation" is not in extension configuration ${JSON.stringify(config)}`);
            }
            PagesDB.open(pages_db_location);
        }).then(() => {

I’ve lightly edited from the actual code to remove some not relevant initialisation.

I just added the code to load the config and it is failing. With the fallback hard-coded location, the extension otherwise runs OK.
