Description

I'm developing an AI chat app, using Inertia, installed boost on the project and whenever the response is a strem I get the followint error:

local.ERROR: str_contains(): Argument #1 ($haystack) must be of type string, false given {"userId":1,"exception":"[object] (TypeError(code: 0): str_contains(): Argument #1 ($haystack) must be of type string, false given at vendor/laravel/boost/src/Middleware/InjectBoost.php:41

vendor/laravel/boost/src/Middleware/InjectBoost.php(41): str_contains(false, '<html')
vendor/laravel/boost/src/Middleware/InjectBoost.php(20): Laravel\\Boost\\Middleware\\InjectBoost->shouldInject(Object(Symfony\\Component\\HttpFoundation\\StreamedResponse))

As soon as I disable boost the error goes away

Steps To Reproduce

Create a laravel 12 project with Inertia and react, install prism or openai-php/client. Send a message from the frontend and create the response of the llm with stream.
