Problem with: "Invalid key supplied", exception: "LogicException" (Laravel v10.26.2)

I had a problem, when I deploy my project into Heroku I try to register but this error comes out I try all solving I search for but doesn’t help me, I use php artisan:migrate, php artisan passport:keys and php artisan passport:install --force, but no one help 🙁

{message: "Invalid key supplied", exception: "LogicException",…}
exception: "LogicException"
file: "/app/vendor/league/oauth2-server/src/CryptKey.php"
line: 67
message: "Invalid key supplied"

public function __construct($keyPath, $passPhrase = null, $keyPermissionsCheck = true)
    {
        $this->passPhrase = $passPhrase;

        if (strpos($keyPath, self::FILE_PREFIX) !== 0 && $this->isValidKey($keyPath, $this->passPhrase ?? '')) {
            $this->keyContents = $keyPath;
            $this->keyPath = '';
            // There's no file, so no need for permission check.
            $keyPermissionsCheck = false;
        } elseif (is_file($keyPath)) {
            if (strpos($keyPath, self::FILE_PREFIX) !== 0) {
                $keyPath = self::FILE_PREFIX . $keyPath;
            }

            if (!is_readable($keyPath)) {
                throw new LogicException(sprintf('Key path "%s" does not exist or is not readable', $keyPath));
            }
            $this->keyContents = file_get_contents($keyPath);
            $this->keyPath = $keyPath;
            if (!$this->isValidKey($this->keyContents, $this->passPhrase ?? '')) {
                throw new LogicException('Unable to read key from file ' . $keyPath);
            }
        } else { // ***** line 67 *****
            throw new LogicException('Invalid key supplied');
        }

        if ($keyPermissionsCheck === true) {
            // Verify the permissions of the key
            $keyPathPerms = decoct(fileperms($this->keyPath) & 0777);
            if (in_array($keyPathPerms, ['400', '440', '600', '640', '660'], true) === false) {
                trigger_error(
                    sprintf(
                        'Key file "%s" permissions are not correct, recommend changing to 600 or 660 instead of %s',
                        $this->keyPath,
                        $keyPathPerms
                    ),
                    E_USER_NOTICE
                );
            }
        }
    }

I want to find what’s is the problem because I try to solve it for a week

finally I find the solution add this in .env

PASSPORT_PRIVATE_KEY="-----BEGIN RSA PRIVATE KEY-----
<private key here>
-----END RSA PRIVATE KEY-----"
 
PASSPORT_PUBLIC_KEY="-----BEGIN PUBLIC KEY-----
<public key here>
-----END PUBLIC KEY-----"

just write your key to be like this

PASSPORT_PRIVATE_KEY="-----BEGIN RSA PRIVATE KEY-----
