1.19.70 broke the /fill command in-game, when you try to fill a location with a block using its data value, the command fails.
For example if you run this command in-game:
/fill 0 0 0 10 10 10 stone 1
It will throw an error. But if you run the command in a .mcfunction file, it will work. The bug is only for in-game chat.
Thank you for your report!
