Could not load email provider "strapi-provider-email-postmark"

Hey guys, I’m trying to deploy strapi in AWS using App Runner but I’ve a problem with an email provider that throws me this error (image)
This is my plugin.js config:

    config: {
      provider: 'strapi-provider-email-postmark',
      providerOptions: {
        apiToken: env('POSTMARK_API_TOKEN'),
      },
      settings: {
        defaultFrom: 'my@email.com',
        defaultReplyTo: 'myother@email.com',
        defaultSubject: 'Subject'
      },
    },
  },
});

My package.json

  "dependencies": {
    "@bn-digital/strapi-plugin-field-uuid": "^1.1.7",
    "@strapi/plugin-graphql": "^4.6.0",
    "@strapi/plugin-i18n": "4.6.0",

    "axios": "^0.21.4",
    "better-sqlite3": "7.4.6",
    "lodash": "^4.17.21",
    "moment": "^2.29.4",
    "postmark": "^3.0.14",
    "strapi-plugin-fuzzy-search": "^1.10.2",
    "strapi-plugin-sitemap": "^2.0.8",
    "strapi-provider-email-postmark": "./providers/strapi-provider-email-postmark",
    "stripe": "^10.7.0",
    "uuid": "^9.0.0"
  },


Any help is appreciated it.
