# 32024: Twilio rejected the request to initiate or modify the call because the Passports parameter failed initial validation checks.

Log Type: APPLICATION

Log Level: ERROR

## Description

Twilio rejected the call request because the passports parameter contained malformed, or structurally invalid data that failed syntax validation.

### Possible causes

The data in the `Passports` parameter doesn't meet the syntax and structural requirements for Programmable Voice Passport Pass-Through. Twilio returns this error when the payload meets any of the following conditions:

* Exceeds the maximum limit of 5 total passports.
* Is malformed, or not properly Base64URL-encoded.

### Possible solutions

To resolve this error, inspect your request and ensure the Passports parameter conforms to the following rules:

* The payload must be a valid, Base64 URL-encoded, comma-separated list of JWT passports.
* Include up to five passports in the decoded array.
* Remove any trailing commas, unescaped quotation marks, or unpadded Base64 strings.
