Unlinking issue when trying to deploy AWS Lambda

I did an example serverless deploy from a blog and had no issues with it. However when I try to deploy my own project I get EPERM: operation not permitted, unlink errors. No errors if I deploy with empty requirements.txt.

I’m wondering if there’s something wrong with my serverless.yml file. But that’s just a wild guess. This is how it looks like.

service: f1-bot

provider:
  name: aws
  runtime: python3.6
  region: eu-west-1
  environment:
    TELEGRAM_TOKEN: ${env:TELEGRAM_TOKEN}
    F1_CHAT_ID: ${env:F1_CHAT_ID}
    CHROME_DRIVER: ${env:CHROME_DRIVER}

functions:
  webhook:
    handler: handler.webhook
    events:
      - http: POST /

  set_webhook:
    handler: handler.set_webhook
    events:
      - http: POST /set_webhook

plugins:
  - serverless-python-requirements

custom:
  pythonRequirements:
    dockerizePip: non-linux
