why do i get suddenly an access denied in the mysql bitbucket pipeline?

[David Michael Gang]

This looks crazy but suddenly my bitbucket pipelines started to fail because access denied.

pymysql.err.OperationalError: (1045, "Access denied for user 'example-user'@'127.0.0.1' (using password: NO)")

Here is my bitbucket-pipelines.yaml file:

# This is a sample build configuration for Python.
# Check our guides at https://confluence.atlassian.com/x/x4UWN for more examples.
# Only use spaces to indent your .yml configuration.
# -----
# You can specify a custom docker image from Docker Hub as your build environment.
image: python:3.6.4

pipelines:
  default:
    - step:
        caches:
          - pip
        script: # Modify the commands below to build your repository.
          - pip install pipenv
          - pipenv install --dev --system --deploy
          - export DB_USERNAME=example-user && export DB_PASSWORD=example-user
          - python -c 'import os;print(os.environ.get("DB_PASSWORD"))'
          - coverage run --source=predictor --omit=predictor/* -m unittest
          - coverage report -m
        services:
          - mysql


definitions:
  services:
    mysql:
      image: mysql
      environment:
        MYSQL_RANDOM_ROOT_PASSWORD: 'yes'
        MYSQL_DATABASE: 'database1'
        MYSQL_USER: 'example-user'
        MYSQL_PASSWORD: 'example-user'

I can confirm that the environment variable is printed. How can i debug the issue further?
