failed to generate the compile_commands.json for proxy_wasm_cpp_host

Hi, thanks for you guys provide so great tools. But I encountered a problem when I wanted to use it in the proxy_wasm_cpp_host.

Here is my build configuration:

refresh_compile_commands(
    name = "refresh_compile_commands",

    # Specify the targets of interest.
    # For example, specify a dict of targets and any flags required to build.
    targets = {
        "//:lib": "--define=engine=multi",
        "//test/...": "--define=engine=multi",
    },
)

Here is error:

    It's probably a generated file, and you haven't yet run a build to generate it.
    That's OK; your code doesn't even have to compile for this tool to work.
    If you can, though, you might want to run a build of your code with --keep_going.
        That way everything possible is generated, browsable and indexed for autocomplete.
    However, if you have *already* built your code, and generated the missing file...
        Please make sure you're supplying this tool with the same flags you use to build.
        You can either use a refresh_compile_commands rule or the special -- syntax. Please see the README.
        [Supplying flags normally won't work. That just causes this tool to be built with those flags.]
    Continuing gracefully...
