Error on tinygo wasip1 example on website

[SeaRoll]

For this code:

package main

//go:wasmimport yourmodulename add
func add(x, y uint32) uint32 {
	return x + y
}

// main is required for the `wasip1` target, even if it isn't used.
func main() {}

and running this command:

GOOS=wasip1 GOARCH=wasm tinygo build -o main.wasm main.go

results in:

main.go:4:6: can only use //go:wasmimport on declarations

Using tinygo 0.33

Edit: more info tinygo version 0.33.0 darwin/arm64 (using go version go1.22.2 and LLVM version 18.1.2)
