Error loading data for bar chart visualization

[AdMSilvan]

Describe the bug
When attempting a barchart visualization of a simple datacube, the data does not load and produces an error. The query is able to retrieve the data but it cannot be loaded in the visualization tool (https://s.zazuko.com/qon2Zo)

To Reproduce
Go to https://int.visualize.admin.ch/create/22Sv3bKjVQGL?dataSource=Int

Expected behavior
A bar chart which can either be filtered by revenue type or represented as a segmented bar chart, stacking the different revenue types

Environment:

• Visualize INT v3.22.4 (211d0fb)

@AdMSilvan thank you for reporting this we will look into it.

Hi @AdMSilvan, it looks like the https://culture.ld.admin.ch/sfa/PolitikfinanzierungParteien2023/einnahmequelle dimension has a langString data type, which Visualize does not support. Would it be possible to change the data type to string? This should fix the issue.

From our side @sosiology, I think we could improve the error message to make it more clear what needs to be done, right now it's not very helpful 👀
