# 35132: Bulk : Provided Attributes JSON is not valid

Log Type: APPLICATION

Log Level: ERROR

## Description

Twilio returns this error when a bulk messaging request includes `Attributes` that are not valid JSON.

### Possible causes

* The `Attributes` value is not valid JSON.
* The attribute payload is malformed or does not match the expected format. This is an inference based on the error text.

### Possible solutions

* Update the `Attributes` value so it is valid JSON before you resend the request.
* Check each attribute for the expected format and correct any malformed fields.
