Export not working for diagrams including conditional formatting and Umlaut
When trying to export a diagram with an Umlaut (ä, ö, ü, etc. in my case capital ‘Ö’), in the chartname I always got the message ‘Due to the size of this document, it may take some time to generate your file. Please keep this document open until your download is complete’. After waiting some time in front of the open document, a message pops up ‘An error occurred. Failed to download’.
Removing the Umlaut from the chartname fixes the issue.
It took me about an hour to find the error, a more concise error message would be nice.
