Hi @Xen-dev
While we are unable to comment on the code shared above, I can confirm that the productCreateMedia mutation can be used with Staged Upload URLs created by the stagedUploadsCreate mutation after the files have been uploaded to the url. The productCreateMedia argument originalSource, can accept both staged URLs and external URLs as well.
More information on the using Staged Upload URLs with the productCreateMedia mutation can be found in our Shopify.Dev documentation. Here are some guides and resources from our documentation that maybe of further help.
- Manage media for products - Shopify.dev
- productCreateMedia - Shopify.dev
- stagedUploadsCreate - Shopify.dev
I hope this helps, and I hope you have a great day
