# 19055: Channel update failed: invalid JSON or non-updatable field

Log Type: APPLICATION

Log Level: ERROR

## Description

This error occurs when your channel update request contains invalid JSON or includes fields that this endpoint does not allow you to update. When you update a channel, only `type`, `description`, and `is_primary` are supported.

### Possible causes

* Your request body contains invalid JSON syntax.
* Your request tries to update fields other than `type`, `description`, or `is_primary`.

### Possible solutions

* Remove unsupported fields from the request body. Update only `type`, `description`, or `is_primary`.
