'.' is not recognized as an internal or external command

If it's helpful in any way, this is the code:

const proc = cp.spawn(`./scripts/${script}.bat`,[], {detached: true})
    const pid = proc.pid;
    console.log(pid);
    message.channel.send(`PID: ${pid}`);
    proc.stdout.on('data', (data) => {
    console.log(`stdout: ${data}`);
    });
    proc.stderr.on('data', (data) => {
    console.error(`stderr: ${data}`);
    });
    proc.on('close', (code) => {
    console.log(`child process exited with code ${code}`);
    });

And the result:

stderr: '.' is not recognized as an internal or external command, operable program or batch file.

child process exited with code 1

While the ${script}.bat looks like:

echo a
