HDEL - wrong arguments

[xeops]

array_key_exists(): The first argument should be either a string or an integer at

vendor/predis/predis/src/ClientInterface.php:69

• @method int hdel($key, array $fields)

Sorry for bad English and describing a problem, but.
When I call hdel like

$this->redis->hdel($key, [$field]);

i have an error

array_key_exists(): The first argument should be either a string or an integer at
m6web/redis-mock/src/M6Web/Component/RedisMock/RedisMock.php:756

But I cant send not array in hdel because in
vendor/predis/predis/src/ClientInterface.php:69
@method int hdel($key, array $fields)
accept only array as second variable.
