Uploading/adding product image to Azure blob fails

nopCommerce version: 4.3
Hosted on Azure app service with azure sql and blob storage enabled

Steps to reproduce the problem:

I'm getting the exception below when i'm trying to add an image to a product.

when uploading it, i can see the thumbnail in the storage container. The normal sized image isn't there
when i click "add picture" there is no thumbnail nor the normal sized image in the blob storage. Also the exception below is thrown when clicking the button.
tried both media settings "pictures are stored into database" and "pictures are stored into file system". Btw which one should it be when using azure blob storage since it isn't documented?
Thanks for your help and advice.

In the upcoming version v4.4 this problem is being taken care of: https://github.com/nopSolutions/nopCommerce/pull/5019

For the current version v4.3, I've made a solution based on the v4.4 implementation. You can find the adaption here: https://github.com/nopSolutions/nopCommerce/issues/5050

That's right, there will be no problem in version 4.40. A working solution for version 4.30 is given in the ticket https://github.com/nopSolutions/nopCommerce/issues/5050. We checked it against the code for 4.40 and taking into account the peculiarities of the new version, everything is identical.
