[5.x]: Error variant missing its inventory item

[jornwildenbeest]

What happened?

Description

Somehow, my best guest is during the upgrade to craft 5 but I am not sure, purchasables where created without inventory.
This results in an error when you want to edit the variant in the cp.

And then there is (as far as I know) no way to re-save the variant or a way to add the inventory for the purchasable manually.

The error:

Hi @jornwildenbeest

Thank you for reporting.

As a matter of testing, in your local development environment can you run the CLI command craft resave/products and let us know if the problem persists?

Thanks!

Hi @nfourtythree

Running the command craft resave/products did indeed fixed the issue.

Thanks

Hi @jornwildenbeest

Glad to hear this fixed it.

Will close this for now but continue to monitor any reports related to this issue.

Thanks!

Hi @nfourtythree,

We have a shop where this exact problem happened a few times now. In January and February we checked for missing inventory items and added them manually to the commerce_inventoryitems table and that fixed the problem for these variants.

We've thought it was maybe due to migrating data when launching the shop, but now 2 months later there are a few new variants with missing inventory items.
So instead of just fixing them by resaving or adding a db record, I wonder if there's a bug in Commerce that leaves purchasables without an inventory item causing an error in the CP.

The shop is running on Craft 5.6.17 and Commerce 5.3.2.2

I have seen the same thing (variants suddenly losing their inventory data with no apparent reason) and am wondering if anyone ever found any clues why this is happening?

Hey folks, thanks for reporting this, sorry on the delay getting back to you.

We would love to see if we could get a copy of your database backup (as well as composer.json and composer.lock) for us to look at, as we haven't been able to reproduce this ourselves.

Please send to support@craftcms.com

Also let us know:

• Are you using any type of import tool like the Feedme plugin?
• Do you have multiple inventory locations?

Thanks!
