The syntax for declaring custom environment variables (under env) has changed.

3.3.0/3.3.1:

...
    env:
      - name: VARIABLE_NAME
        value: "variable value"

3.4.0:

...
    env:
      VARIABLE_NAME:
        value: "variable value"

The properties are migrated by calling the Python helper script. Make sure the output file complies with the description of the example above.
