You’re probably using tab characters to indent your YAML file.

This is not permitted by the YAML spec:

To maintain portability, tab characters must not be used in indentation, since different systems treat tabs differently. Note that most modern editors may be configured so that pressing the tab key results in the insertion of an appropriate number of spaces.
