EntityMetadataWrapperException: Unknown data property commerce_product.

This is most often due to a failure to install the correct fields. Does your product type actually have the stock field on it successfully?

Note that Commerce Repair is made for this situation in general. But more for Commerce core... not sure what it would do here.

But I also note you're using 7.x-2.x of stock? That's pretty experimental still, as far as I understand.

douggough@drupal.org thanks for helping test V2
I got a few of questions that may help me figure out the issue:
1) Is this a fresh install and you didn't install stock V1 before the V2 version?
2) Did you only enable the API module without the Simple Stock (should be possible)?
3) Did you clear caches before testing?

Its strange that function commerce_stock_check_cart_product_level() is raising errors as its only checks what the order currently holds for the product (doesn't use the stock field), i have also added this feature to V1 (dev) so would like to make sure the function works.

is it possible for you to give me a archive/copy of your installation site and DB (if it contains no personal info), may make it easier to debug if i cant recreate the issue.

@douggough@drupal.org the entity_metadata_wrapper call should be ok the syntax expects the $type a commerce_order and $data (object /instance) the actual order and the $info array is optional.
This syntax is used all over commerce in places like the cart module:
// If the user actually has a cart order...
if ($order = commerce_cart_order_load($user->uid)) {
// Count the number of product line items on the order.
$wrapper = entity_metadata_wrapper('commerce_order', $order);

it is strange that this line of code should fail only on the stock module, are you shore you are not getting this error when the stock module is disabled?

ill try and test on a fresh install of kickstart but it is possible something may have gone wrong with D6 Ubercart using the Migrate import.

@douggough@drupal.org lust tested on a fresh install of he latest kickstart with no other modules except stock v2 and the kickstart products and no problems (not that it proves there are no issues).

if you are sure this only happens when stock is enabled the only thing i can suggest is debugging your site if you can provide a sensitized copy.

Why don't you share it with me, and I'll take this one off of Guy's 1000 things to do. I'll PM you the email to dropbox it to.

thanks Randy, let me know how you get on

glad it sorted, let us know how you got on

I have the same error

EntityMetadataWrapperException: Unknown data property commerce_product. in EntityStructureWrapper->getPropertyInfo() (line 339 of /home/.../public_html/sites/all/modules/entity/includes/entity.wrapper.inc).

but in another situation.

When in Checkout settings I move the Shipping service pane from the Shipping page to the Checkout page.

When I disable stock api everything is ok with an empty Shipping Page.

I am using the latest commerce and stock v2 dev. my backtrace is:

Thanks in advance for your help

Im facing the same issue on 7.x-1.x, after activating Stock, click add to cart.
Strangely it doesnt happen for anonymous.
Tried uninstall and install again with the same result.

Thanks!

i think we have a fix for this see http://drupal.org/node/1290842, a fix should be in by monday

I have the same issue (2.x-dev). Here are the steps I performed :

• Fresh install with Commerce Kickstart
• Enabled the Commerce Stock API and Simple Stock modules
• Activated the stock on Product type : Product
• Added stock on products

Then the site is not available for the admin user (see the attached image) but I still can access the overlays (as an admin) and the site works fine for anonymous user (even the check on stock quantity) !

Hope this can help.

Waiting for monday ;)

thanks GuGuss, i think i know what the problem is but if my suspicion is correct you must have another module installed most likely shipping.
can you pls confirm if you have other modules installed.

committed a patch for both V1 and V2 that should fix this, dev version tomorrow should include it.
