Hello,

After following the directions on [this](https://serverless.com/blog/api-gateway-multiple-services/) custom domain article, I was able to setup custom domain for my flask service which I created by following this article: [https://serverless.com/blog/flask-python-rest-api-serverless-lambda-dynamodb/](https://serverless.com/blog/flask-python-rest-api-serverless-lambda-dynamodb/)

My serverless.yml is as following:

```
service: fleet-api
app: fleet-api

plugins:
  - serverless-python-requirements
  - serverless-wsgi
  - serverless-domain-manager

provider:
  name: aws
  runtime: python3.6
  stage: dev
  region: eu-central-1
  environment:
    SERVICE_NAME: ${self:service}

functions:
  app:
    handler: wsgi_handler.handler
    events:
      - http: 'GET /'
      - http: 'GET /users'

custom:
  stage: ${opt:stage, self:provider.stage}
  wsgi:
    app: main.app
    packRequirements: false
  pythonRequirements:
    dockerizePip: non-linux
  domains:
    prod: api.mydomain.com
    dev: staging-api.mydomain.com
  customDomain:
    domainName: ${self:custom.domains.${self:custom.stage}}
    basePath: 'fleet'
    stage: ${self:provider.stage}
    createRoute53Record: true

```

When I leave basePath empty instead of ‘fleet’, I am able to get results from my endpoints but when I wanna fill it with `fleet`, I get the following response:

```
# Not Found

The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again. 

```

Any idea what’s wrong in my setup?

According to the [serverless-wsgi](https://github.com/logandk/serverless-wsgi) document, you have to set the API\_GATEWAY\_BASE\_PATH environment variable as _fleet_

```auto
provider:
  name: aws
  runtime: python3.6
  stage: dev
  region: eu-central-1
  environment:
    SERVICE_NAME: ${self:service}
    API_GATEWAY_BASE_PATH: fleet

```
