deno.run not working as expected

const p=Deno.run({
    cmd: `mysql --defaults-extra-file=./tmpcnf_from_f_execute_query.cnf -e "DROP DATABASE test_database"`.split(" "),
    stdout: 'piped',
    stderr: 'piped',
    stdin: 'null' 
});
await p.status();
console.log(new TextDecoder().decode(await p.output()));
console.log(new TextDecoder().decode(await p.stderrOutput()));
