Issue while using swaggerUI

[ajeetraina]

@VladyslavHaiko I am facing the below issue while trying to run this app locally.

Steps to reproduce:

1. Run Docker container with RedisGraph compiled

docker run -d -p 6379:6379 redislabs/redismod

2. Clone this repo

git clone https://github.com/redis-developer/basic-redisgraph-movie-demo-app-nodejs

3. Set up environmental variable

Create .env file under the root directory of this repo and add entries like shown below:

ajeetraina@Ajeets-MacBook-Pro basic-redisgraph-movie-demo-app-nodejs % cat .env 
REDIS_HOST=redis://localhost
REDIS_PORT=6379
REDIS_DB=
REDIS_PASSWORD= 
REDIS_GRAPH=graphtest 

4. Install dependencies

npm install

5. Run server

node app.js

6. Open localhost:3001/docs and try to hit POST /genres

Error: node_redis: The GRAPH.QUERY command contains a invalid argument type of "undefined".
Only strings, dates and buffers are accepted. Please update your code to use valid argument types.
