Image upload Universal

Hi,

I've set up an image column with an image_upload domain.

This is how the domain is set up:

The ‘azure image’ storage location is configured like this:

Where the user name is the storage account name and the password is key 1 from the Acces keys page for that particular storage. 

All seems right to me so far. But when I opend the tab where this column is located I get an unknown error:

This error can't be found in the logs and Redux isn't showing me anything to fix either.

I know it's the image column that causes the error, because when I change the domain to something random like a varchar, the page loads fine.

I'm on Universal GUI 2022.2.15

Anyone has an idea what it could be?
