unsupported_option

The option '{0}' isn't supported by '{1}'.

The analyzer produces this diagnostic when an unsupported option is specified.

The following code produces this diagnostic because experiments isn't a supported option:

// %uri="analysis_options.yaml"
analyzer:
  experiments:
    - augmentations

If you intended to use a supported option, then replace the unsupported option with the supported one:

// %uri="analysis_options.yaml"
analyzer:
  enable-experiment:
    - augmentations

If no option exists for your intended purpose, then remove the unsupported option:

// %uri="analysis_options.yaml"
analyzer:
