invalid_username at token/validate

Prerequisites

• [ x] I am running the latest plugin version
• [ x] I am running the latest WordPress version
• [ x] I know what PHP version I'm using
• [ x] I checked the documentation and found no answer
• [ x] I checked to make sure that this issue has not already been filed

Context

• WordPress version 6.4.2
• PHP Version 8.1
• JWT Authentication for WP-API 1.3.4

Expected Behavior

/wp-json/jwt-auth/v1/token/validate

Http status: 200

/wp-json/wp/v2/users

Http status: 200

Current Behavior

/wp-json/jwt-auth/v1/token/validate

Http status: 500 Internal Server Error

{
    "code": "invalid_username",
    "message": "<strong>Error:</strong> The username <strong>{\"typ\"</strong> is not registered on this site. If you are unsure of your username, try your email address instead.",
    "data": null
}

but....

/wp-json/wp/v2/users

Http status: 200

Failure Information (for bugs)

/wp-json/jwt-auth/v1/token?username=user&password=secret

Is working and gets me the token. But trying to validate does not work...

.htaccess file

#Begin JWT auth
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^(.*) - [E=HTTP_AUTHORIZATION:%1]
</IfModule>
SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1
#End JWT auth

And the wp-config.php also contains:

define('JWT_AUTH_SECRET_KEY', 'secret-hash');
define('JWT_AUTH_CORS_ENABLE', true);

Fixed it by removing some other plugins....
