Empty geometryCollection field returning error on access

[viniterra]

Hi, I am having an issue with a geometry collection field . At some point, I have to update the field removing all points inside it. The problem is when I try to obtain an object from the DB and then get the field as an array.

It seems that the cast for an empty geometry collection is erroneous:

FatalThrowableError (E_ERROR) Call to a member function toArray() on string

The error occurs when calling:
$obj->waypoints->toArray()

A dump for the object returns the field as:
"waypoints" => "\x00\x00\x00\x00\x01\x07\x00\x00\x00\x00\x00\x00\x00"

The SQL query for the field, using ST_AsText(waypoints) returns:
GEOMETRYCOLLECTION()

I declare the field in the migration as:
$table->geometryCollection('waypoints');

and declare as a spatial field on the model class:
protected $spatialFields = [ 'waypoints' ];

On SpatialTrait, line 96:

if (in_array($attribute, $spatial_fields) && is_string($value) && strlen($value) >= 15)

I don't know why you set the length condition to 15, but changing it to 13 (which is the length of the string "\x00\x00\x00\x00\x01\x07\x00\x00\x00\x00\x00\x00\x00") solved the cast.

I truly don't remember why there's a check for >= 15. I'm going to do a quick search and test without the condition.

What's the WKT representation of the binary mentioned?

The WKT is the empty geometry collection:

"GEOMETRYCOLLECTION()"
