Bug Report

Error Description
Target Domain does not match endpoints domain. In fact Target Domain is a random combination of letters on every deployment and always just keeps changing!

Going over to the custom domain, I get:

{
    "message": "Forbidden"
}

Command Run
npx sls deploy --stage dev --region eu-west-1

Console Output

✔ serverless-better-credentials: credentials resolved from config SharedIniFileCredentials: provider.profile (dev)

Deploying project to stage dev (eu-west-1)

✔ Service deployed to stack project-dev (37s)

endpoints:
  GET - https://abcdefg123.execute-api.eu-west-1.amazonaws.com/health
functions:
  health: project-dev-health (16 kB)
layers:
  DepsLayer: arn:aws:lambda:eu-west-1:...:layer:DepsLayer:10
Serverless Domain Manager:
  Domain Name: subdomain.of.site.com
  Target Domain: xyzhjkr743.execute-api.eu-west-1.amazonaws.com
  Hosted Zone Id: ZCLDTFWJFENWEF

Improve API performance – monitor it with the Serverless Console: run "serverless --console"

Possible Solution
Downgrading to rest does the trick

Hi @adminy

The Target Domain is the API Gateway domain name and it's not a bug
