/tellraw command color reset no longer exists

I was working on a datapack that has multiple tellraw sections, and noticed the color reset isn't working as it should

/tellraw @s [\{"text":"-1 ","color": "red"},\{"text":"secondary test","color": "reset"}] 

what this should do is color the first part red, but remove the specified color from the second part, leaving it whatever color it is normally, whether it's a letter or custom glyph, but at the moment, the game is saying the term "reset" doesn't exist, and if I leave it colorless, the second line takes the color from the first line.
