Hi there,

Trying to run “kitty-items-js” by following its instruction on “kitty-items” GitHub page:

However, there seems to be an error related to password authentication ( see below ):

> flow-kitty-items@0.0.1 start:dev  
> tsnd --respawn src/index.ts

[INFO] 01:28:04 ts-node-dev ver. 1.1.1 (using ts-node ver. 9.1.1, typescript ver. 4.1.2)

When you look at “docker-compose.yml”, the environment is as below:

* * *

```
environment:
  - POSTGRES_DB=kittyitems
  - POSTGRES_USER=kittyuser
  - POSTGRES_PASSWORD=kittypassword

```

* * *

Any advises would be appreciated. Thanks!

I think it may be caused by postgres\_db set-up on Windows. Perhaps the port “5432” is being used by other programs.

Anyone who has similar experience on Windows? Please kindly share the solution.

Thanks!
