Describe the Bug

Observed behavior

On npm run deploy I get the error triggers.map is not a function.

Expected behavior

I would have expected the app to deploy.

Steps to reproduce

This is my basic project index.js file

/**
 * This is a template for a Scheduled Worker that updates TLD data from DNSimple
 * and stores it in Redis. The worker is triggered based on the schedule defined
 * in the wrangler.toml configuration.
 */

export default {
    async scheduled(event, env, ctx) {
        event.waitUntil(handleScheduledEvent());
        console.log(`Update triggered at ${event.scheduledTime}`);
    },
};


async function handleScheduledEvent() {
    const dnsimpleApi = 'https://api.dnsimple.com/v2/tlds';

    try {
        // Fetching TLD data from DNSimple
        const response = await fetch(dnsimpleApi);
        const jsonData = await response.json();
        const tlds = jsonData.data;

        // Update each TLD in Redis
        for (const tld of tlds) {
			await env.KV_TLD_SYNC.put("tld", tld.tld);       
        }
    } catch (error) {
        console.error('Error in scheduled event:', error);
    }
}

This is my Wrangler.toml file

I don't see why this error is happening. Any help would be greatly appreciated.

crons expects an array, so if you change your wrangler.toml to include:

crons = ["0 * * * *"]

it should work as expected.
