Hi Community,

I am having issues working with schedules & accessing Data Storage API from the serverless app.

When i tried using schedule and db in server.js, it throws an error ReferenceError: $db is not defined & ReferenceError: $schedule is not defined

I have attached the screenshots of the error. Please help me resolve this issue.

Schedule Code Snippet :

$schedule
	.create({
		name: `service_task_${data.ticketId}`,
		data: { taskData: data },
		schedule_at: time
	})
	.then(
		(data) => console.log(data),
		(err) => console.log(err)
	)

DB Code Snippet :

$db.set("ticket:101", { taskId: 15213 }).then(
	function (data) {
		console.log(data)
	},
	function (error) {
		console.log(error)
	}
)

DB Error :

db-error
db-error2266×520 42.3 KB

Schedule Error :

schedule-error
schedule-error2257×531 39.7 KB

FDK Version :

Thanks,

Hi Arshath,
May I know under which event handler is this snippet written?

Hi @ManiDeepak_Vandrangi,

Thanks for your reply.

I have used it in onScheduleEvent & my custom method in server.js.

 exports = {
       events: [{ event: "onScheduledEvent", callback: "onScheduledEventHandler" }],

      onScheduledEventHandler: function (payload) {
	     handler.scheduleHandler(payload)
      },
      serviceTask: function (payload) {
	     handler.serviceTaskHandler(payload)
	     renderData()
      }
}

Hi Arshath,

Are you trying to invoke this event from custom installation page? If so, in custom installation, we do not support data storage($db) and schedule($schedule).

Hi @ManiDeepak_Vandrangi,

I have used the $schedule & $db in server.js file.

BTW, i am not receiving the error anymore in my machine. I don’t know what was the reason for the error. And, don’t know how it resolved automatically :upside_down_face:.

Thanks for your reply.

Is the error same as above mentioned screenshots for the above mentioned snippets? If so, are you using the latest version of fdk?

@ManiDeepak_Vandrangi Yes same error, we receive this often. Then suddenly it resolves automatically. Could you please help find us the issue?

@arshath.h does this happen in FDK events testing or when you try to use the end to end testing feature?

Hi Community,

In local, recurring schedule It’s working properly. Error occurs only time based schedule.

Solution:
Publish and install your custom app in portal. It should works proper.

thanks.
