How can I get my .env file to working properly

I have been trying to run the node create.js to get the data table but the terminal returns error code: Missing_auth_field, Missing fields in token context. I had tried several methods to debug it like checking my .env file and seeing that the logo of the .env file appears to be a cog-wheel, not the paper logo. I assume that the error occurred because my .env file is not working properly, can anyone tell me if my assumption is right or not?
