strapi is not defined when connect use promise

[jm1jm2jm]

When the connect() method returns with a promise it causes strapi is not defind

class SftpClient {
  constructor() {
    this.conn = new Client();
  }

  connect() {
    return new Promise((resolve, reject) => {
      this.conn
        .on("ready", () => {
          this.conn.sftp((err, sftp) => {
            if (err) return reject(err);
            sftp.readdir(remoteDir, (err, list) => {
              if (err) return reject(err);
                 .....do something 
            });
          });
        })
        .connect({
          host: host,
          port: "8000",
          username: username,
          password: password,
        });
    });
  }
}

module.exports = {
  sync: async (ctx, next) => {
    await next();

    const sftpClient = new SftpClient();
    try {
      await sftpClient.connect();
      console.log(sftpClient.fileData, "sftpClient.data");
      await strapi.entityService.findOne(
        "api::xxx.xxx",
        1,
      );
    } catch (err) {
      console.error(err);
      return { message: "Failed to sync" };
    } finally {
    }
  },
};

That error has nothing to do with ssh2. You're missing whatever library is providing that object.
