 Fix deployment issue [@Irfan Wicaksana](#user_mention#88979479)

ISSUE: It works fine when accessing it from a pod/service using port forwarding, but it does not work when accessing it using the domain https://metarank.hhstaging.dev . Maybe the issue is with the load balancer. Please help resolve it, Mas @Irfan Wicaksana.

 BullMQ check events `https://personalize.hungryhub.com/bullmq`

```
 Impression Event
```
```
 Interaction Event
```

Post Release @Luthfi

 Disable Impression & Interaction event worker

```
 Load restaurants data
```
```
 Load users data
```

 Enable Impression & Interaction event worker

 Wait the data collection for 1 or 1/2 day for initial training

NOTE: To train Metarank, impression events are necessary. Currently, we do not have these events, so we need to collect them before train the model.

 Validate the training data

 Pull the data from s3 using jupyter notebook

```
 Validate the data
```

 Train the model (try in local standalone cmd first)

```
 Train the model (production)
```

 Test the API using production build preview

```
 Enable the Growthbook Feature Flag
```

https://growthbook.hungryhub.com/features/search-ranking

 All users with "@hungryhub.com" email addresses will always get personalized search results.

 Then, we'll gradually roll out to other users, starting with 5% and gradually increasing while monitoring the service.
