Problem creating import content plugin

System Information
  • Strapi Version: 3.2.5
  • Operating System: Windows 10
  • Database: MongoDB
  • Node Version: v12.18.1
  • NPM Version:
  • Yarn Version: v1.22.4

Good morning, i am trying to create the strapi import plugin: How to create your own plugin on strapi (3/4). Everything is fine until point 3, when I implement:

1- “Open ImportContent.js file inside controllers directory, remove the default content and paste the following”:

"use strict";
module.exports = {
  preAnalyzeImportFile: async ctx => {
    const services = strapi.plugins["import-content"].services;
    try {
      const data = await services["importcontent"].preAnalyzeImportFile(ctx);
    } catch (error) {
      ctx.response.status = 406;
      ctx.response.message = "could not parse: " + error;

2- “Open routes.json inside config directory and paste the following”

  "routes": [
      "method": "POST",
      "path": "/preAnalyzeImportFile",
      "handler": "ImportContent.preAnalyzeImportFile",
      "config": {
        "policies": []

Until that moment, I had not thrown any errors. When I implement the above two points, it throws me an error:

error TypeError: Cannot read property ‘preAnalyzeImportFile’ of undefined

I have tried to understand why, but I don’t have much experience to solve the problem.

Thanks in advance.

Same here. Did you find any solution, considering this forum is pretty old?
