# 92004: Invalid language code

Log Type: APPLICATION

Log Level: ERROR

## Description

This error appears when you create Content with a `language` value that is not valid for the resource. The Content API uses a two-letter ISO 639-1 language code, and Content Templates are limited to one language per template.

### Possible causes

* You sent a `language` value that is not a valid two-letter ISO 639-1 code.
* The language you chose is not supported for the Content template you are creating or updating.

### Possible solutions

* Set `language` to a supported two-letter ISO 639-1 code, such as `en`.
* If you need to send content in more than one language, create a separate Content template for each language.
