This method seems to be duplicated in your project.

It seems like you do not handle an error condition here. This can introduce security issues, and is generally not recommended.

It seems like $defaultException can also be of type object<Exception>. However, the property $defaultException is declared as type object<Http\Client\Exception>|null. Maybe add an additional type check?
