This error message indicates that there is an issue with the formatting of the YAML file located at “/root/recommended.yaml”. The parser is unable to convert the YAML content into JSON format due to a syntax error on line 22. Specifically, it seems that a colon character was expected but not found.
To fix this error, you will need to carefully review the content of the YAML file and make sure that all syntax rules are followed correctly. This may involve checking for missing or extra punctuation marks, ensuring that indentation is consistent throughout the document, and verifying that all key-value pairs are properly formatted.
Once you have corrected any errors in the YAML file, you should be able to successfully parse it into JSON format without encountering any further issues.
