Did u add the master key to your dotenv file? looks like u didnt

[alymurtazamemon]

@ritesh798 Make sure your file name is .env because most people forget to rename the .env.example file that they download while cloning the repo.

@ritesh798 There are two possibilities of why the error occurs (with straight-forward, self-explanatory fixes):

• Make sure you have the .env in your root directory; carefully verify the naming convention as well for typos

• Finally, if the above was correct, make sure you have a masterKey (process.env.masterKey); fix any different naming scheme to avoid typos/desync w/ the actual convention followed (i.e. `masterKey)).
