It's happening to me as well. Please help. Thanks.

It happens when you have a column like this: tags list,

But you never set a value to such column (of list type)

Hi I am getting this too.

I have columns that do not always have data and in these circumstances I get this error.

Would love to see a fix for this soon ish otherwise not sure I can release this into production as it casuses no end of notice errors for me.

Thanks

I fixed it in my fork https://github.com/aslubsky/php-cassandra-binary Fix is not very good (dirty try cath) but work and may be used as temporary solution

[evseevnn-zz]

ok, I'll try to fix it tomorrow during the day

Hi did get around to looking at this?

[steambao]

Can confirm this occurs when reading NULL'ed MAP<><> column types as: readShort() is trying to get a count from an empty $this->data string (len = 0).

Like aslubsky, did a temp fix in my fork 344ae09d1c856717337f4c9491bf2e46f77d1d88

There is a general problem with NULL values. I used the development branch and added all the ($isCollectionElement = false) parameters in DataStream.php from the master branch. That fixed the Problem with the maps. The most important change was adding this:

    public function readByType(array $type, $isCollectionElement = false) {
        if (strlen($this->data) <= 0){
            return null;
        }
