I'm also facing internal server error on my store, How to resolve it. Urgent help required.

Store: stylo.pk

Hi,

The ValueError: Expected singleton error in Odoo occurs when a method that expects a single record (singleton) is called on multiple records. Odoo methods often assume they will be called with a single record, so if the method is called with multiple records, this error is raised.

To solve this issue we can use a for loop to handle multiple records is a common approach to fix the ValueError: Expected singleton error in Odoo. This allows you to process each record individually, ensuring that methods designed for single records can handle multiple records.

Hope it helps.

hiii vishnu, what i have to do to fix this error.

Vishnu V Nath

you can give limit=1,
or
view = request.website.viewref("website_sale.product")
if len(view) != 1:
raise ValueError("Expected a single view record, found %d." % len(view))
view_track = view.track

Vishnu V Nath

view_id = request.env['ir.ui.view'].search([('key', '=', 'website_sale.product')], limit=1)

if not view_id:

raise ValueError("Product view not found")

view_track = view_id.track
