The error is in your aura: 'DataTests-WarMode', which is using a api that Blizzard removed in 9.0

This github is about reporting bugs in the weakauras addon and not about bugs in some weakaura that you are using.

You might get help in the weakauras discord. https://discord.com/invite/wa2

By either:

• Deleting the aura, or
• Updating the aura if there's a newer version of it, or contacting the author if there isn't, or
• Fixing the code yourself.
