I tried to override the wooden_button.json advancement by using:

 

{
    "criteria": {
        "impossible": {
            "trigger": "minecraft:impossible"
        }
    }
}

and placing it in the path:

.../morebeautifulbuttons/advancements/recipes/redstone/

but I get the error:

What do I need to do?

I don't think it's possible to override vanilla advancements without messing around with the internals of the advancement system, since mod advancements are loaded with the mod ID as the domain of the advancement ID.

 

You can suppress this error message by overriding the minecraft:wooden_button recipe with a no-op IRecipe as diesieben07 suggested here.

Since how do I suppress this error.

Did you read the post I linked?

Yes!

Which part didn't you understand? Do you know how to create the replacement recipe? Do you know how to override a registry entry?

@Issac29 Please don't necro an old thread (this thread is over a year old) and please don't hijack someone else's thread - make your own.

What are you trying to do (please describe it in end-user terms not how you've attempted to program it)?

Please include your code (the JSON recipe).
