After updating my applications dependencies this morning i started getting this error when a validator chain contains isFLoat

AssertionError

File:

```
/var/www/eap/vendor/laminas/laminas-i18n/src/Validator/IsFloat.php:242

```

Message:

```
assert($lastStringGroup !== '')

```

my validator and filter chain are set in the getInputFilterSpecification of my form like so:

```auto
 [
    'name' => 'min_gpa',
    'validators' => [
        [
            'name' => 'NotEmpty',
        ],
        [
            'name' => 'IsFloat',
            
        ],
    ],
    'filters' => [
        ['name' => StripTags::class],
        ['name' => StringTrim::class],
    ],
],

```

Before today if it was empty it would say “a value is required”. now i get the exception.

Any help would be greatly appreciated.

Can you give an example value that can be used to reproduce the problem?

If the field min\_gpa is blank it used to return the Value is required. Now if its blank it throws the Assertion Error. It also Doesn’t matter if i put the NotEmpty before or after the isFloat.

My mistake, I had overlooked the fact that it was an empty string.
