Error: When using the axios package in TypeScript code within a Firebase cloud function, there is an issue with reading the property 'post' which is undefined

I am attempting to implement the following logic in a Google Cloud Function. When I run this function using the emulator, I consistently encounter the error message

⚠  functions: TypeError: Cannot read property 'post' of undefined

I have tried importing the Axios package in various ways without success. Could this issue be related to my code or is there a configuration setting in Firebase that I am overlooking?

import axios from "axios";

export const sendSlackMessage = functions.https.onRequest(async (request, response) => {
  const slackUrl = functions.config().slackconfig.webhookurl;
  await axios.post(slackUrl, request.body)
    .then((value) => {
      console.log(value.data);
      response.sendStatus(200);
    })
    .catch((reason) => {
      response.send(`Failed, ${reason}`);
    });
});

Answer №1

Ensure that axios is installed in the designated functions folder

 navigate to functions/
 install axios using npm
