We have a webshop running TC 3.2.4 were we sometime see a wierd error.
The error is here :
2019-01-31 13:53:16,297 [P12732/D3/T8] ERROR BlueHors.Models.Shop.ShopContext - Violation of PRIMARY KEY constraint 'PK_TeaCommerce_OrderLinePrice_1'. Cannot insert duplicate key in object 'dbo.TeaCommerce_OrderLinePrice'. The duplicate key value is (3481, 3).

If we look at shopcontext.cs line 108 we actually just set a vat group:
And its not a constant bug, it just on browsing, or if we search for a product through lucene. I dont know if it has something to do with it, but it might be when we hit something alot of times quickly, like a search api.
Any ideas? Im really hitting bottom on this one and cant seem to figure out why.
That's an interesting one. What database tech are you using? SQL Server? SQL Azure?
Yeah its an odd one, and we see on multiple places of the solution, I was thinking if it was part of some sql pooling or something that made it come out.
Its on a 100 DTU Azure SQL. Not doing anything special in the connection string, so all basic umbraco setup.
Hmm, the only thing I know of currently is that TC uses it's own implementation of PetaPoco which doesn't have transient fault handling like the Umbraco Core does, but if that was the issue, I'd expect requests to be failing rather than running multiple times.
Hmm yeah that is wierd :/
Is their a way we can come this any closer? Im guessing the code where the error is thrown is comming from the closed source part of TC.
WIll it be an option to send you a zip of the project? and how to force it "down"?
Sure, we can certainly try.
Drop us an email at firstname.lastname@example.org with a copy of your project (please make sure it doesn't contain any customer data) and instructions for getting setup / replicating the issue and we can see what we can figure out.
