Google spreadsheet is loaded to chart via .csv correctly, but not via URL

Hi there,

I would like to share a table via google spreadsheet. The table is prepared according to your article here:https://docs.themeisle.com/article/607-how-can-i-populate-data-from-google-spreadsheet, but when I insert Google spreadsheet ′s URL into a chart, is not working. Plugin Visualiser writes this: Invalid data types in second row.

But when I download the same tables as .csv to my computer and upload it to the chart, it is working. So the table is made correctly.

So, where is the problem?

Here is the URL for the google spreadsheet:
