Debugging "The step provided was invalid"

Michael Ritter

I'm trying to setup PHP unit testing for our PHP application using MariaDB as a "service".

Now, as soon as I declare that my step should use the service defined in "definitions" section the pipeline fails with the message "The step provided was invalid". Whenever I remove the service from the step it works.

According to https://bitbucket-pipelines.atlassian.io/validator my bitbucket-pipelines.yml is valid.

What am I doing wrong? What does the error mean? How can I debug that error?

I currently use the following bitbucket-pipelines.yml for testing:

 

clone:
  depth: 1
pipelines:
  default:
    - step:
        image: php:7.0-apache
        script:
          - ls
        services:
          - maria
definitions:
  services:
    maria:
      image: mariadb
      environment:
        MYSQL_ALLOW_EMPTY_PASSWORD: 'yes'
        MYSQL_ROOT_PASSWORD: ''
        MYSQL_DATABASE: 'dev'

Hello,

The issue is that you have an empty string for the value of the MYSQL_ROOT_PASSWORD. Pipelines fails to parse this as it is a string with no content.

An alternate way of setting the MYSQL_ROOT_PASSWORD variable to an empty string is to set MYSQL_ROOT_PASSWORD="\0".

Thanks,

Phil
