[1.17] Problems caused by moving to 1.17 in my mod

I was developing on 1.16.5 until yesterday and moved it to 1.17, but I'm having two issues.

1. Crash when use custom liquid bucket. Displayed ""this.fluid" is null", but I don't think it should be null because the liquid is properly registered ...

error log:

custom fluid bucket is here : https://github.com/Zemelua/UMU-Arcanum/blob/main/src/main/java/io/github/zemelua/umu_arcanum/item/UMUArcanumItems.java

 

 

2. It seems that the biome is not registered. The other day, I encountered a similar error in 1.16.5, and at that time I just forgot to register the deferred register, but the error is displayed even though I registered properly this time.

 Also, this time the error biome id is -1 instead of 174 (the first index of the mod biome).

error log:

custom biome register is here : https://github.com/Zemelua/UMU-Arcanum/blob/main/src/main/java/io/github/zemelua/umu_arcanum/world/biome/UMUArcanumBiomes.java
and data is here : https://github.com/Zemelua/UMU-Arcanum/blob/main/src/main/resources/data/umu_arcanum/worldgen/biome/dim_forest.json

 

It took me a long time, but I couldn't figure out why this was happening. Help me.

PS: Is this a possible 1.17 mapping issue? I'm using the official 1.17 mapping.
