TypeError when sending transactional SMS in PHP 8.4

[kyegil]

PHP version 8.4.22
getbrevo/brevo-php version 4.0.13

When sending Transactional SMS, the API response causes the following TypeError:
Cannot assign float to property Brevo\TransactionalSms\Types\SendTransacSmsResponse::$messageId
in Brevo\TransactionalSms\Types\SendTransacSmsResponse line 52

The response messageId is wrongly interpreted as float.

Thanks for the report. We reproduced this. The cause is that messageId is typed as a strict integer, but for large message identifiers PHP decodes the JSON value as a float (this occurs when the value exceeds the platform integer maximum, and on 32 bit PHP builds it can occur with smaller values too). Assigning that float to the int typed property then throws the TypeError you saw.

The correct fix is to widen the type so it accepts the decoded value. Because that turns the property into a float, it is a small but technically breaking change, so we are scheduling it for an upcoming version rather than a patch, to avoid surprising integrators who rely on the int type. We will reference this issue in that release.

Worth noting: v5 is releasing soon. The 4.x line will continue to receive fixes, and once v5 is out we recommend migrating to it. If this is currently blocking you, let us know and we will prioritize accordingly.
