Is there a reference for supported anchor IDL types, just like we have for the space reference. Trying to use a slice [usize; 32] but getting the error

IdlError: Type not found: {"type":{"defined":"usize"}}

To add to this, how can I pass in "bytes" from the anchor client side. The parameter is defined like this on my anchor program

fn dummy(bytes: Vec<u8>) -> Result<()> {}

Try using a u8 slice instead of usize, the latter has a variable size depending the system. All primitives are supported, and your own structs made of primitives, and a few other types like Pubkey, the rest is a hard maybe.

On the TS client side, you can pass a number[] or a Buffer.
