Deno.cron scheduled to run once daily executes 6 times daily

I have a cron job on Deno deploy that is supposed to send a Telegram message daily at 5:00. Each day at 5:00, I receive 6 messages.

await Deno.cron("send-name-day", "0 5 * * *", () => {
  const nameDays = [ ... ];
  const date = new Date();
  const month = date.getMonth() + 1;
  const day = date.getDate();
  const nameDay = nameDays[month - 1][day - 1];
  
  const path = `https://api.telegram.org/bot${Deno.env.get("TOKEN")}/sendMessage`;
  const resp = fetch(path, {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      chat_id: XXXXXXXXXX,
      text: `${day}/${month}: ${nameDay}`,
    }),
  });
  console.log(resp.json());
});

await Deno.cron("send-name-day", "0 5 * * *", () => {
  const nameDays = [ ... ];
  const date = new Date();
  const month = date.getMonth() + 1;
  const day = date.getDate();
  const nameDay = nameDays[month - 1][day - 1];

    }),
  });
  console.log(resp.json());
});

Any help would be greatly appreciated!

In the meantime, you can maybe try to store the last time a cron job was invoked in deno kv to prevent messages from being sent in succession.

Moved this to Val Town and am using their cron functionality for scheduling. Would love to move it back to Deno Deploy eventually if the issue can be resolved.
