Firebase cloud functions working in emulator, but failed to deploy

Question

I am working for a mini project, I need to call an external api but I could not deploy the function, I am having a the following error,

Error: There was an error deploying functions

I could not find anything in firebase-debug.log. when I called the same function as http triggered function and test it from the emulator, it worked, However, I could not deploy.

exports.scheduledFunction = functions.pubsub.schedule("every 1 minute").onRun(async (context) => {
  const response = await getResponse();
  functions.logger.log(response);
  return null;
});

function getResponse() {
  const url = "https://pikas.techinsight.com.my/kgateway/testing.php";
  return new Promise((resolve, reject) => {
    axios.get(url).then((response) => {
      return resolve(response.data.split("\n"));
    }).catch((error) => {
      functions.logger.log(error);
      return reject(error);
    });
  });
}

Here's the debug.log

Please help me to see what i am doing wrong

Check if you have installed all your dependencies inside /functions folder. I had installed some dependencies in the root of the project by a mistake. The emulator is still able to resolve those dependencies but deployment fails.
