golang application project, which never wakes up from sleeping.

Question

I have a golang application running, which gets put to sleep when there is no request.
Now, after a while when i manually made some calls to the api to wake it up, it never wakes up. Any idea on how to fix this?
I will share my deploy schema: 
```{
  "$schema": "https://railway.com/railway.schema.json",
  "build": {
    "builder": "NIXPACKS",
    "buildCommand": "go build -o main ."
  },
  "deploy": {
    "runtime": "V2",
    "numReplicas": 1,
    "startCommand": "./main",
    "healthcheckPath": "/",
    "sleepApplication": true,
    "multiRegionConfig": {
      "asia-southeast1-eqsg3a": {
        "numReplicas": 1
      }
    },
    "restartPolicyType": "NEVER",
    "healthcheckTimeout": 100
  }
}```
