How to solve "ContextErrorException in ProductAssembler.php line 88" PrestaShop (1.7.0.5)

[HugeB]

Hi,

 

if i change main language i recivie error:

ContextErrorException in ProductAssembler.php line 88:

Notice: Undefined offset: 0

 

Full error can be seen here on site:

http://hugebuy.eu/de/2507-perfumes-cosmetics

 

On default language it's OK.

 

How can i solve that? I don't know where to start resolving, because error page don't tell me anything, or?

 

Thank you!

Regards.

UPDATE: I disabled DEBUG mode in backoffice, and now languages loads without error. It's that normal for PrestaShop?

debug mode should  only be enabled when actively debugging but if left on can result in unpredictable results.  this is not an uncommon issue across more complex (cart based) cms's. really anything that uses .js can fall over pretty easy...lol

I highly recommend upgrading 1.7.0.5 to latest stable as this was a very early release.

Hello!

In my case, the problem is not in code, it is in database.

Error apears when the user has in his favourite list a deleted product. Then, PrestaShop tries to load this product, but it cannot find it.

Solution is search all references of deleted product IDs in table st_loved_product, in the id_source field. You must delete these rows, and error should disappear.

Good luck!

This can happen also with modules saving the product IDs to use in some arrays, and then using ProductAssembler. It happened with ETS Mega Menu, adding products in the product list widget. After deleting a product the module still asks for that ID and Prestashop gives this error. The solution is to update the module configuration, deleting the missing product.

Yes i think it's normal since the debug mode is not made for normal use, except you need to read error details or get other dev stuff
