I just forget to annotate the method with @Insert.

fun insertAll(postDbModels: Array<PostDbModel>)

Just adding @Insert fixed this.

@Insert
fun insertAll(postDbModels: Array<PostDbModel>)

to

@Delete

@JesúsBarrera from the comments is correct. check your imports. the annotation should be like this

@Delete

android studio will probably import this

import androidx.room.*

if not already present
