Docker development question: unable to view products after production data import?

[jayaddison]

Hello OpenFoodFacts community,

I use Docker for local software development of OpenFoodFacts.

Usually I use the small sample dataset of ~100 products -- not the entire OpenFoodFacts database (4,000,000+ products!).

Yesterday to investigate #14058 I began a complete production import using make import_prod_data.

The import completed after roughly 1 hour and 30 minutes.

Now I can query the OFF MongoDB database, and it shows that the entire product dataset is loaded:

$ docker exec -it off_shared-mongodb-1 bash
# mongo off
> db.products.count()
4643705

However.. when I try to browse one of the products using the local web interface, I get an error message saying that no product data is found.

For example, when I visit this URL: http://world.openfoodfacts.localhost/product/8719587326060/skyr-albert-heijn

...I get a message saying Error - No product listed for barcode 8719587326060. (screenshot below).

Does anyone know what causes this?

Some debugging I have attempted:

I increased the log verbosity, because I found that mentioned in the Docker development guide: https://github.com/openfoodfacts/openfoodfacts-server/blob/main/docs/dev/how-to-develop-using-docker.md#increasing-log-verbosity

...and then I noticed some errors/messages in the logs saying that the product files cannot be found on the filesystem. I'm not sure this is relevant, but maybe it is?

$ docker exec -it po_off-backend-1 bash
# grep 8719587326060 /mnt/podata/logs/log4perl.log
...
[2026/07/28 19:35:40] [8463] [DEBUG] /opt/product-opener/lib/ProductOpener/Products.pm 1067 [retrieve_product] {"full_product_path":"/mnt/podata/products/871/958/732/6060/product","request":"MfUmgzkwQDXA23Vs","rev":null,"product_id":"8719587326060","code":"8719587326060"}

...

There are not many files under /mnt/podata/products -- certainly not 4 million. And the product's path does not exist at all:

$ find /mnt/podata/products -type f | wc -l
565
$ ls -l /mnt/podata/products/871/958/732/6060
ls: cannot access '/mnt/podata/products/871/958/732/6060': No such file or directory
$ ls -l /mnt/podata/products/871
ls: cannot access '/mnt/podata/products/871': No such file or directory

Have I missed a step in the production data import process that should fill the /mnt/podata/products directory with product data files?

Thank you!
James

This may have been due to existing/stale data in my Docker environment.

After stopping all containers and recreating 100-product dev environment, I encountered the same No product listed for barcode ... error for products in the small/sample dataset.

After a subsequent complete prune of all containers and also all volumes (e.g. persistent Docker storage), I do not encounter the problem in a fresh 100-product dev env.

At some point soon I will re-attempt the complete 4M+ dataset in a completely fresh environment (after again removing all persistent Docker volumes/storage).
