Escaping double quotes in windows commands

问题

I am trying to run a sample test using Jest to verify if my Google Cloud Function is working fine or not but I am constantly getting following error.

Error: Command failed: gcloud beta functions call cf-1 --region europe-west1 --data '{"data":"eyJkYXRhIjoiMSJ9"}'
ERROR: (gcloud.beta.functions.call) Invalid value for [--data]: Is not a valid JSON: No JSON object could be decoded

I know that i can escape double quotes with backslash when running the command in windows terminal but how to do it in JavaScript.

test.js

const childProcess = require('child_process');

describe('Test CF', () => {
    it('print outs the error message when received JSON is blank', done => {
        const msg = { data: '1' };
        const encodedMsg = Buffer.from(JSON.stringify(msg)).toString('base64');
        const data = JSON.stringify({ data: encodedMsg });
        const executeResultOutput = childProcess.execSync(`gcloud beta functions call cf-1 --region europe-west1 --data '${data}'`).toString();

        const logs = childProcess
            .execSync(
                `gcloud functions logs read cf-1 --region europe-west1 --execution-id ${executionIdObj}`,
            )
            .toString();

        expect(logs).toEqual(expect.stringContaining('Error..'));
    });
});

Try it twice:

data = {"data":"eyJkYXRhIjoiMSJ9"}
console.log(
  JSON.stringify(JSON.stringify(data))
)
