Image file format webm not allowed in media library upload

Hi. You can upgrade Strapi to the latest version following these guides : Migration Guides | Strapi Documentation

module.exports = ({ env }) => ({
  // ...
  upload: {
    config: {
      provider: 'cloudinary',
      providerOptions: {
        cloud_name: env('CLOUDINARY_NAME'),
        api_key: env('CLOUDINARY_KEY'),
        api_secret: env('CLOUDINARY_SECRET'),
      },
      actionOptions: {
        upload: {},
        uploadStream: {},
        delete: {},
      },
    },
  },
  // ...
});

hope it helps. I’m using the file webm located in : https://dl6.webmfiles.org/big-buck-bunny_trailer.webm
