You need to add your mysql username and passw to the '.env' file.

For example, my .env file looks like this:

CLOUD_NAME = '*********'
CLOUDINARY_API_KEY = '***************',
CLOUDINARY_SECRET = '****************'
MYSQL_USERNAME = 'root'
MYSQL_PASSW = 'password'
EAGER_URL = 'https://multi.loca.lt/eager_endpoint'

Then run the following commands:

npm i

npx sequelize-cli db:drop

npx sequelize-cli db:create

npx sequelize-cli db:migrate

npx sequelize-cli db:seed:all

npm start

Then on a new terminal run:

lt --port 8084

Copy the generated url to .env file's EAGER_URL

Localtunnel allows larger files to be uploaded to cloudinary
