Parameter name: bytes | Double check the [field mappings](search-indexer-field-mappings.md) defined on the indexer, and compare with the data of the specified field of the failed document. It may be necessary to modify the field mappings or the document data. |

 ### Skill input 'languageCode' has the following language codes 'X,Y,Z', at least one of which is invalid.
 One or more of the values passed into the optional `languageCode` input of a downstream skill is not supported. This can occur if you are passing the output of the [LanguageDetectionSkill](cognitive-search-skill-language-detection.md) to subsequent skills, and the output consists of more languages than are supported in those downstream skills.
