Today I’m getting this error when I go to sales->orders – “Item (MagentoFrameworkViewElementUiComponentDataProviderDocument) with the same ID “19” already exists.”
Searching the error isn’t bringing up any useful fixes. I haven’t changed any config or deleted any products. Some extensions were updated yesterday, Braintree/PayPal being one of them.
Can anyone advise how to resolve this please?
Thanks in advance!
