I wanted to add crops that the sprinkler could grow and seeing that there was no relevant config created, I looked inside the mod and found sprinkler_growable.json file in the tags folder. Unfortunately, making any changes to the file just crashes the game.

For example, I added wheat seeds as the following :

{
"replace": false,
"values": [
"minecraft:sweet_berry_bush",
"minecraft:wheat_seeds"
]
}

I tried both ways of indentation, with a TAB and with FOUR SPACES, but neither seem to work.
Below is an attachment of the crash log.

What's the problem here? Is it on the mod's side or mine? Perhaps incompatible java version? I was using the latest version of java until recently, when 1.16.5 forge servers could not be run with them (client ran just fine) so I had to find out that Java 8 was compatible and manually downgrade so.
