# Troubleshooting Tasks

> Fix common Tasks issues: requests that don't arrive, requests that disappear, staff who can't sign in, and missing sounds.

## Requests don't arrive, or the solution shows an error when sending one

Endless Aisle shows "An error occurred while creating order", and Smart Fitting Room shows "Ooops, something went wrong".

1. Check that the queue is open: in Tasks, **Settings** → **The queue is open**
2. Check that the solution's Tasks setting points to this Tasks installation, and not to a Queue Management queue
3. Check that staff have the staff board of the same installation open
4. Check that the device sending the request is online

## Requests disappear from the board after Deliver

1. Turn on **Show serving tab (Enable ticket check out)** in the Tasks settings. Without it, the board has no **For Payment** column, so delivered requests leave the board and can't be completed

## Staff can't sign in

1. With **Pin code** login, check that staff use the PIN set in the Tasks settings
2. With **Email** login, check that the staff member has been invited to your tenant and has accepted the invite. See [Invite a user](https://learn.phystack.com/users/invite-a-user/)
3. Check that staff open the address ending in `/admin`

## An empty request appears on the board

Opening the Tasks address without `/admin` at the end opens the customer page, which creates a new, empty request.

1. Remove the empty request with **Remove**
2. Bookmark the address that ends in `/admin` on staff devices

## There's no sound for new requests

1. Turn on **Enable audio notification** in the Tasks **Settings** on each staff device. It's off by default
2. Keep the staff board open. The sound only plays while the board is open in the browser
3. Check that the device's sound is on

## Items can't be marked as picked

1. Check that the products have **EAN** barcodes in **Content** → **Products**. Items are marked by scanning their barcode
2. Allow the browser to use the device camera when Tasks asks for it
3. If the scanner shows "Scanner is not available", check that the device has a camera and that no other app is using it
