Problem with axios post request from Nuxt.js to external API

I’m trying for many hours now, to get a simple post request to my external api working from Nuxt.

It works as expected from a seperate node instance, I can POST and GET as needed with the following:

const headers = {
  'Content-Type': 'application/json',
  'access-token': 'myTokenXYZ123'
};
const data = { test: 'Hello!' };

const postSomething = () => {
  axios.post('https://myapidomain.com/api', data, {
    headers: headers
  });
};
postSomething();

Also with curl:

curl -X POST -H 'access-token: myTokenXYZ123' -H 'Content-Type: application/json' -d '{ "test": "Hello!" }' https://myapidomain.com/api

So far so good, now I want to implement this in my Nuxt project. I had to set up a http proxy first, which I did in nuxt.config.js like this:

[...]

modules: [
    '@nuxtjs/axios',
    '@nuxtjs/proxy'
  ],
  proxy: {
    '/my-api/': { target: 'https://myapidomain.com/api', pathRewrite: {'^/my-api/': ''} },
  },
  axios: {
    proxy: true
  },

[...]

I’m pretty confident that the proxy is working, because I can get the data with the following method:

methods: {
  async getSomething() {
    let requested = await this.$axios.get('/my-api/', {
       headers: this.headers
    });
    return requested.data;
  }
}

But whatever I do, the POST request does not work. This is how I tried:

methods: {
  postSomething() {
    const data = { test: 'Hello!' };

    this.$axios.post('/my-api/', data, {
      headers: {
        'Content-Type': 'application/json',
        'access-token': 'myTokenXYZ123'
      }
    });
  }
}

I tried various different formats, e.g. like this:

methods: {
  postSomething() {
    const headers = {
      'Content-Type': 'application/json',
      'access-token': 'myTokenXYZ123'
    };
    const data = { test: 'Hello!' };
    const options = {
      method: 'post',
      url: '/my-api/',
      data: data,
      transformRequest: [(data, headers) => {
        return data;
      }]
    };
    this.$axios(options);
  }
}

But it does not seem to work. The request is running and aborts after a while with the following error in the terminal:

ERROR  [HPM] Error occurred while trying to proxy request  from localhost:3000 to https://myapidomain.com/api (ECONNRESET) (https://nodejs.org/api/errors.html#errors_common_system_errors)

A few other things I already tried:

Running API and Nuxt locally
Using axios imported in template and as nuxt module
Request from builded and productive version
Async and synchronous methods

Steps to reproduce:

# Download and start API server
git clone https://github.com/consuman/api-demo.git
cd api-demo/
npm install
node src

# In a second terminal download and start Nuxt server
git clone https://github.com/consuman/api-demo-nuxt.git
cd api-demo-nuxt
npm install
npm run dev

# Navigate to http://localhost:3000
# Relevant code is in /api-demo-nuxt/pages/index.vue

To test, if the API is working, you can POST with curl:

curl -X POST -H 'access-token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJjaGVjayI6dHJ1ZSwiaWF0IjoxNTg2MTYzMjAxLCJleHAiOjE2MTc2OTkyMDF9.vot4mfiR0j6OewlJ0RWgRksDGp-BSD4RPSymZpXTjAs' -H 'Content-Type: application/json' -d '{ "testData": "Hello from API, posted from curl, please overwrite me!" }' http://localhost:3001/api

Thank you for reading. Any hint would be much appreciated!

I have found the problem. There was a server middleware configured, that was not needed anymore. It triggered at every POST request.

Stupid mistake, but this is how you learn, right? xD

The steps to reproduce are a working demo now, in case anyone needs something similar.

Cheers!

Here is the working demo again:

# Download and start API server
git clone https://github.com/consuman/api-demo.git
cd api-demo/
npm install
node src

# In a second terminal download and start Nuxt server
git clone https://github.com/consuman/api-demo-nuxt.git
cd api-demo-nuxt
npm install
npm run dev

# Navigate to http://localhost:3000
# Relevant code is in /api-demo-nuxt/pages/index.vue
