Hydrating an active order only applies prices to the variant of the first order line

[martijnvdbrug]

Describe the bug When hydrating an active order with applyProductVariantPrices=true, only the variant of the first order line has pricing applied, the other will have price 0;

To Reproduce Steps to reproduce the behavior: (see e2e test below)

1. Create an active order with 3 items
2. Fetch the active order
3. Hydrate the active order
4. order.lines[0].productVariant.price will be 155880, while order.lines[1].productVariant.price will be 0.

5. Adding the variants in a different order will result in the same issue: it's always only the first variant that will have pricing applied.

Expected behavior I would expect all the variants to have the correct pricing.

Environment (please complete the following information):

• @vendure/core version: 1.9.2
• Nodejs version: 16
• Database (mysql/postgres etc): SQLite

Additional context You should be able to just copy and paste the test case below.

Hi Martijn,

It took me a while to get round to this, but I just added your tests to the existing entity-hydrator.e2e-spec.ts suite and it passed. So I'm suspecting that this somehow got fixed between 1.9.2 -> 2.0.5?

Have you run into this in the latest versions?

In any case, I'll leave the e2e tests in the suite to ensure this does not regress.

[martijnvdbrug]

Thanks for looking into this. Unfortunately the issue still persists on my end. I've created a reproducable setup here: (It is using Vendure 2.0.5) https://github.com/Pinelab-studio/_temp_aug_2023_vendure_issue2013_repro

You can

1. git clone git@github.com:Pinelab-studio/_temp_aug_2023_vendure_issue2013_repro.git
2. yarn
3. yarn test
4. And see the last 2 tests failing:

 ❯ testing.spec.ts (4) 5162ms
   ❯ Hydration issue (4) 5162ms
     ✓ Create order with 3 items 302ms
     ✓ Variant of orderLine 1 has a price
     × Variant of orderLine 2 has a price
     × Variant of orderLine 3 has a price

Thanks. This lead me to discover that I can reproduce the error when using postgres / sqlite - but it works with mysql, mariadb & sqljs! I'll look into how to fix...

[martijnvdbrug]

Strange :disappointed: I remember last time we had an issue that was DB specific, it was caused by the order in which arrays were returned...

EDIT: nvm, I see it's already closed, nice!
