Trying to get property 'vendor' of non-object

Hello, Im new to this framework.Did anyone know what happen with this, Thank you

$userVendor is null and you’re trying to get its property. That’s exactly what’s stated in the error message.

To be more precise, your DB query (findOne()) did not return a result. You have to check if ($userVendor !== null) { ... } before using it.

I would also suggest to move the, query and (if check) in your controller

Thankyou everyone.
