Nodejs Elastic benastalk refused to connect to upsteam/ upsteam prematurely closed

Question

I am getting the following errors when running my application in elastic beanstalk: [error] 3636#0: *295 upstream prematurely closed connection while reading response header from upstream and [error] 3636#0: *295 connect() failed (111: Connection refused) while connecting to upstream Its strange because if I hit those routes independently it works fine. It only appears to error when firing those routes from my vuex action.

The following is the log from the AWS elastic beanstalk.

The following is the network tab when it hits my FFmpeg route:

The following is the generate video action as fired from vuex.

  async [GENERATE_VIDEO]({state, rootState, dispatch, commit}){
          const username = rootState.user.currentUser.username;
          const s3Id = rootState.templates.currentVideo.stock_s3_id;
          const type = rootState.dataClay.fileFormat || state.type;
          const vid = new Whammy.fromImageArray(state.captures, 30);
             vid.lastModifiedDate = new Date();
             vid.name = "canvasVideo.webm";
          const data = new FormData();
          const id = `${username}_${new Date().getTime()}`;
          data.append("id", id);
          data.append("upload", vid);
          const projectId = await dispatch(INSERT_PROJECT);
          await dispatch(UPLOAD_TEMP_FILE, data);
      const key = await dispatch(CONVERT_FILE_TYPE, { id, username, type, projectId});
      const role = rootState.user.currentUser.role;
      state.file = `/api/files/${key}`;
      let message;
      if(role!='banner'){
        message =`<p>Your video is ready.</p> <a href="${state.file}" download class="btn btn-primary btn-block">Download</a>`;
      } else {
        message = `<p>Your video is ready. You may download your file from your banner account</p>`;
        const resolution = rootState.dataClay.matrix[0];
        await dispatch(EXPORT_TO_BANNER, { s3Id, fileUrl: key, extension: `.${type}`, resolution});
      }

And here are the api routes called in the actions.

 async [UPLOAD_TEMP_FILE]({ commit }, data) {
    try {
     const response = await axios.post("/api/canvas-editor/upload-temp", data);
     return response.data;
    } catch (error) {
      console.log(error);
    }
  },
async [CONVERT_FILE_TYPE]({commit}, data) {
    try{
    const response = await axios.post("/api/canvas-editor/ffmpeg", data);
    return response.data;
    } catch(error){
        console.log(error);
    }
  }
  }

As I said all my routes work and the application runs as expected on localhost however when uploaded to aws I receive unexpected errors.

After some digging I found out that I did not set the ffmpeg path. Once this was done it worked great.

const ffmpeg = require('fluent-ffmpeg');
const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path;
ffmpeg.setFfmpegPath(ffmpegPath);

module.exports = ffmpeg;
