$in missing double quote Guid

[Marvinnnne]

I try to use $in and i face this issue :
"Invalid JSON. A comma character ',' was expected in scope 'Array'. Every two elements in an array and properties of an object must be separated by commas."

This is the filter done by $in
$filter=(Microsoft.Dynamics.CRM.In(PropertyName=%27cap_productinformationid%27,PropertyValues=[7F2E937A-5D3F-EF11-840A-6045BD8C9F94,912E937A-5D3F-EF11-840A-6045BD8C9F94,D72E937A-5D3F-EF11-840A-6045BD8C9F94]))

It's missing " between Guid in the array. This should be

$filter=(Microsoft.Dynamics.CRM.In(PropertyName=%27cap_productinformationid%27,PropertyValues=["7F2E937A-5D3F-EF11-840A-6045BD8C9F94","912E937A-5D3F-EF11-840A-6045BD8C9F94","D72E937A-5D3F-EF11-840A-6045BD8C9F94"]))

We try to update the file dg.xrmquery.web because we think it's linked to this method getVal() but without success.
